DESCRIPTION:Title: Van Est differentiation and Van Est integration\nby Eckhard Mein
renken (Toronto) as part of Global Poisson webinar\n\nLecture held in Zoom
.\n\nAbstract\nThe classical Van Est theory relates the smooth cohomology
of Lie groups with the cohomology of the associated Lie algebra. Some aspe
cts of this theory generalize to Lie groupoids and their Lie algebroids. I
n this talk\, we revisit the van Est theory using the Perturbation Lemma f
rom homological algebra. This leads to precise descriptions of the van Est
differentiation and integration at the level of cochains. The talk is bas
ed on recent work with Maria Amelia Salazar.\n

DESCRIPTION:Title: Short star-products for filtered quantizations\nby Pavel Etingof
(MIT) as part of Global Poisson webinar\n\nLecture held in Zoom.\n\nAbstr
act\nLet $A$ be a filtered Poisson algebra with Poisson bracket $\\lbrace{
\,\\rbrace}$ of degree $-2$. A {\\it star product} on $A$ is an associativ
e product $*: A\\otimes A\\to A$ given by $$a*b=ab+\\sum_{i\\ge 1}C_i(a\,b
)\,$$ where $C_i$ has degree $-2i$ and $C_1(a\,b)-C_1(b\,a)=\\lbrace{a\,b\
\rbrace}$. We call the product * {\\it even} if $C_i(a\,b)=(-1)^iC_i(b\,
a)$ for all $i$\, and call it {\\it short} if $C_i(a\,b)=0$ whenever $i>{\
\rm min}({\\rm deg}(a)\, {\\rm deg}(b))$.\n\nMotivated by three-dimensiona
l $N=4$ superconformal field theory\, In 2016 Beem\, Peelaers and Rastelli
considered short even star-products for homogeneous symplectic singularit
ies (more precisely\, hyperK\\"ahler cones) and conjectured that that they
exist and depend on finitely many parameters. We prove the dependence on
finitely many parameters in general and existence for a large class of exa
mples\, using the connection of this problem with zeroth Hochschild homolo
gy of quantizations suggested by Kontsevich.\n\nBeem\, Peelaers and Rastel
li also computed the first few terms of short quantizations for Kleinian s
ingularities of type A\, which were later computed to all orders by Dedush
enko\, Pufu and Yacoby. We will discuss some generalizations of these resu
lts.\n\nThis is joint work with Douglas Stryker.\n

DESCRIPTION:Title: Holonomic Poisson manifolds\nby Brent Pym (McGill) as part of Gl
obal Poisson webinar\n\nLecture held in Zoom.\n\nAbstract\nHolonomicity is
a new sort of nondegeneracy condition for\nholomorphic Poisson structures
\, closely related to the notion of a log\nsymplectic form\, and intimatel
y connected with the geometry of\nWeinstein's modular vector field. It e
ncompasses many natural Poisson\nstructures arising in gauge theory\, repr
esentation theory\, and algebraic\ngeometry. The motivation for the defi
nition comes from deformation\ntheory: a Poisson manifold is holonomic whe
n its space of deformations\nis "as finite-dimensional as possible"\, in a
sense I will make precise\nduring the talk (via D-modules). I will desc
ribe the basic theory and\nexamples of holonomic Poisson manifolds\, along
with some concrete\nclassification results\, including the discovery of m
any new irreducible\ncomponents of the moduli space of Poisson fourfolds.

DESCRIPTION:Title: From b-Poisson manifolds to singular contact structures\nby Eva
Miranda (UPC) as part of Global Poisson webinar\n\nLecture held in Zoom.\n
\nAbstract\nTaking as starting point motivating examples from celestial me
chanics and fluid dynamics\, we introduce the odd-dimensional counterpart
of b-Poisson/log-symplectic structures as Jacobi structures with transvers
ality conditions.\nWe discuss the basic theory and some constructions. In
particular\, we prove that a connected component of a convex hypersurf
ace of a contact manifold can be realized as a connected component of the
critical set of a $b^m$-contact structure. In dimension 3\, this construct
ion yields the existence of a generic set of surfaces $Z$ such that the pa
ir $(M\,Z)$ is a $b^{2k}$-contact manifold and $Z$ is its critical hypersu
rface.\n\n We also consider classical problems in Hamiltonian/Reeb dynam
ics and address the Weinstein conjecture on the existence of periodic orbi
ts of the Reeb vector field in this singular set-up. We end up this talk w
ith some applications of this singular Weinstein conjecture to the motivat
ing examples discussed at the beginning.\n\nThis is joint work with Cédri

DESCRIPTION:Title: Differential character valued momentum maps and the Teichmüller spa
ce\nby Tudor Ratiu (EPFL and Shanghai) as part of Global Poisson webin
ar\n\n\nAbstract\nIt is well-known that the actions of several diffeomorph
ism groups of geometric interest do not admit momentum maps. The definitio
n of the Teichmüller space via Riemannian geometry strongly suggest that
it is a symplectic reduced space. I will present an extension of the class
ical momentum map which always exists for actions of diffeomorphism groups
possessing the crucial Noether property. This extended momentum map has n
o longer values in (pre)duals of Lie algebras\; its values are in differen
tial character groups. This extended momentum map encodes discrete topolog
ical information\, something the classical momentum map cannot do. In orde
r to focus the presentation\, the Teichmüller space will serve as the exa
mple of this theory. The talk is based on joint work with Tobias Diez from
TU Delft.\n

DESCRIPTION:Title: Quantum minimal surface and noncommutative Kaehler geometry\nby
Maxim Kontsevich (IHÉS) as part of Global Poisson webinar\n\n\nAbstract\n
I will talk about several interrelated topics\, based on works 1903.10792
and 2003.03171. Minimal surfaces in Euclidean space can be approximated (i
n sense of Berezin-Toeplitz quantization) by representations of Yang-Mills
algebra given by relations $\\forall i\\\,\\sum_j[X_j\,[X_j\,X_i]]=0$ whe
re $X_i$ are self-adjoint operators. Similarly\, complex affine curves are
approximated by representations of hermitian Yang-Mills algebra $\\sum_k
[Z_k^\\dagger\,Z_k]=\\hbar\\cdot id$ where $Z_i$ are commuting operators (
but not self-adjoint in general). I will explain how the latter equation a
ppears in the context of a version of Kaehler geometry for noncommutative
algebras.\n

algebras has a geometric version for Poisson manifolds (due to Xu)\, def
ined in terms of Weinstein's dual pairs. A natural question is whether the
se two parallel Morita theories could be related by quantization. Motivate
d by this question\, this talk will discuss an extension of Morita equival
ence of Poisson manifolds to the setting of {\\em formal} Poisson structur
es\, and present a result characterizing Morita equivalent formal Poisson
structures vanishing in zeroth order in terms of ``B-field transformations
'' (joint work with I. Ortiz and S. Waldmann). Using the correspondence be
tween formal Poisson structures and star products (due to Kontsevich)\, th
is result leads to a concrete link between Morita equivalence in Poisson g

DESCRIPTION:Title: Semiclassical aspects of quantization: Local symplectic groupoids\,
generating functions and the Poisson sigma model\nby Alajandro Cabrer
a (UFRJ) as part of Global Poisson webinar\n\n\nAbstract\nThe aim of this
talk is to present three results related to local symplectic groupoids i
n connection to quantization of the underlying Poisson manifold. We first
review the notion of a generating function $S$ for such local symplectic g
roupoids and outline the first result stating that such $S$ always exist a
nd how to construct them. When the Poisson manifold is a coordinate space\
, we provide an explicit (integral) formula for $S$. The second result mak
es reference to quantization: we show that the formal Taylor expansion $S_
K$ of the coordinate $S$ yields the tree-level part of Kontsevich's quanti
zation formula\, as first studied by Cattaneo-Dherin-Felder. We also sketc
h how the (non-formal) analytic formula for $S$ actually "explains" the gr
aph structure of $S_K$\, using Butcher series techniques. Finally\, the t
hird result relates $S$ to the functional perspective underlying the Poiss
on Sigma Model: we can recover $S$ by evaluating a functional on a set of
solutions ("semiclassical fields") for a system of PDEs on a disk\, which
we also show how to solve (non-perturbatively). We comment on conclusions
and further directions at the end.\n

DESCRIPTION:Title: Calculus up to Homotopy on the Space of Solutions of a PDE\nby
Luca Vitagliano (University of Salerno) as part of Global Poisson webinar\
n\n\nAbstract\nEvery partial differential equation (PDE) can be encoded in
a geometric object\, what is sometimes called a diffiety\, which is a sub
manifold of an appropriate type in an infinite jet space. There is a Lie a
lgebroid naturally attached to a diffiety\, and the associated Lie algebro
id cohomology contains important coordinate independent information on the
PDE: variational principles\, symmetries\, conservation laws\, recursion
operators\, etc. To some extent these cohomologies can also be interpreted
as vector fields\, differential forms\, tensors\, etc. on the space of so
lutions. This interpretation is supported by the fact that we find the app
ropriate algebraic structures in cohomology. I will review this theory and
show that those algebraic structures do actually come from homotopy algeb
ras at the level of cochains\, confirming an old conjecture of A. M. Vinog
radov that “the calculus on the space of solutions of a PDE is a calculu
s up to homotopy”.\n

DESCRIPTION:Title: Newton-Okounkov bodies\, integrable systems\, and convergence of po
larizations\nby Megumi Harada (McMaster University) as part of Global
Poisson webinar\n\n\nAbstract\nLet $X$ be a smooth irreducible complex alg
ebraic variety of dimension $n$ and $L$ a very ample Hermitian line bundle
. In this talk I will recount\, in very broad strokes\, two interconnected
stories related to the symplectic geometry of $X$. The first story is tha
t the theory of Newton-Okounkov bodies\, and the toric degenerations to w
hich they give rise\, can provide -- in rather general situations -- const
ructions of integrable systems on $X$. The main tool in the first story is
the gradient-Hamiltonian vector field. The second story concerns the ``in
dependence of polarization'' issue which arises in the theory of geometric
quantization. Specifically\, given a toric degeneration of $(X\,L)$ satis
fying some technical hypotheses\, we construct a deformation $\\{J_s\\}$ o
f the complex structure on $X$ and bases $B_s$ of $H^0(X\, L\, J_s)$ so t
hat $J_0$ is the standard complex structure and\, in the limit as $s \\to
\\infty$\, the basis elements approach dirac-delta distributions centered
at Bohr-Sommerfeld fibers of the moment map associated to the integrable s
ystem on $X$ (constructed using the first story). This significantly gene

DESCRIPTION:Title: From Poisson Geometry to (almost) geometric structures\nby Mari
us Crainic (Utrecht University) as part of Global Poisson webinar\n\n\nAbs
tract\nI will report on an approach to general geometric structures (with
an eye on integrability) based on groupoids endowed with multiplicative st
ructures\; Poisson geometry (with its symplectic groupoids\, Hamiltonian t
heories and Morita equivalences) will provide us with some guiding princip
les. This allows one to discuss general "almost structures" and an integra
bility theorem based on Nash-Moser techniques (and this also opens up the
way for a general "smooth Cartan-Kahler theorem"). This report is based on
collaborations/discussions with Francesco Cataffi (almost structures)\, I
oan Marcut (Nash-Moser techniques)\, Maria Amelia Salzar (Pfaffian groupoi
ds).\n

for the most part to the `geometric case' of a subalgebra of the Lie alge
bra of vector fields on a manifold. This gives a direct quantization with
corresponding algebras (and modules) of pseudodifferential operators. In p
articular I will make the case that the notion of a groupoid is inadequate
here even though there is as yet no precise replacement for it.\n

DESCRIPTION:Title: Classifying space $BG$ as a symplectic stack\nby Chenchang Zhu
(Göttingen) as part of Global Poisson webinar\n\n\nAbstract\nIt is proba
bly well known to people who know it well that $BG$ carries a sort of sym
plectic structure\, if the Lie algebra of $G$ is quadratic Lie algebra.
In this talk\, we explore various differential-geometric (1-group\, 2-grou
p\, double-group) models to realise this (2-shift) symplectic structure in
concrete formulas and show the equivalences between them.\n\nIn the infin
ite dimensional models (2-group\, double-group)\, Segal's symplectic form
on based loop groups turns out to be additionally multiplicative or almost
so. These models are equivalent to a finite dimensional model with Carta
n 3-form and Karshon-Weinstein 2-form via Morita Equivalence. All these fo
rms give rise to the first Pontryagin class on $BG$. Moreover\, they are r
elated to the original invariant pairing on the Lie algebra through an exp
licit integration and Van Est procedure. Finally\, as you might have guess
ed\, the associated String group $BString(G)$ may be seen as a prequantiza
tion of this symplectic structure. From the math-physics point of view\, w
hat is behind is the Chern-Simons sigma model.\n

DESCRIPTION:Title: Coregular submanifolds and Poisson submersions\nby David Martí
nez Torres (PUC-Rio) as part of Global Poisson webinar\n\n\nAbstract\nThis
talk discusses aspects of the theory of submanifolds and submersions in P
oisson geometry. In the first part we present the general picture concerni
ng manifolds which inherit a Poisson structure from an ambient Poisson man
ifold\, and among those\, we select a class (coregular submanifolds) which
have particularly nice functorial properties. The second part is devoted
to Poisson submersions with coregular fibers. Coregular submersions restri
ct nicely over symplectic leaves in the base (coupling property)\, and we
determine when they split into commuting vertical and horizontal Poisson s
tructures. In the last part we present instances in which such coregular P
oisson submersions appear. Our illustrations all revolve around Poisson ac
tions of Poisson-Lie groups. This is joint work with L. Brambila and P. Fr
ejlich.\n

DESCRIPTION:Title: Lie Groupoids and differential equations\nby Francis Bischoff
(University of Oxford) as part of Global Poisson webinar\n\n\nAbstract\nTh
is talk will discuss applications of Lie groupoids to the study of differe
ntial equations with singularities. Several classes of singular differenti
al equations\, or flat connections\, can be recast as representations of L
ie algebroids\, and by integration\, correspond to Lie groupoid representa
tions. This perspective allows us to introduce new tools to the study of t
hese equations. In this talk\, I will give an overview of this approach\,
with a focus on the case of differential equations with logarithmic singul
arities along certain (possibly singular) submanifolds that are associated
to reductive groups. Whereas the traditional approach to classification r
elies heavily on the use of power series\, I will explain how the use of L
ie groupoids gives rise to a more geometric approach.\n

DESCRIPTION:Title: Semiclassical limits of Feigin-Odesskii elliptic algebras via deriv
ed geometry\nby Zheng Hua (University of Hong Kong) as part of Global
Poisson webinar\n\n\nAbstract\nIn 1980s\, Feigin and Odesskii constructed
the elliptic algebras $Q_{n\,k}(C\,\\eta)$ generalizing the construction o
f Sklyanin and Cherednik. Here n\,k are coprime positive integers\, $C$ is
a complex elliptic curve and $\\eta$ is a point on $C$. Elliptic algebras
are quantization of polynomial algebras. They are conjectured to be regu
lar in the sense of Artin and Schelter for all parameters. Homological a
nd representation theoretical properties of elliptic algebras are studied
via Poisson geometry of their semiclassical limits. We will discuss variou
s results about these Poisson structures\, e.g. classification of symplect
ic leaves\, bihamiltonian structures and so on. The main technical tool is
derived geometry\, in particular the work of Calaque-Pantev-Toen-Vaquie-V
ezzosi. This is based on the joint work with Alexander Polishchuk.\n

DESCRIPTION:Title: Deformations\, cohomology and homotopy of relative Rota-Baxter Lie
algebras\nby Yunhe Sheng (Jilin University) as part of Global Poisson
webinar\n\n\nAbstract\nRota-Baxter operators were originally defined on a
commutative associative algebra by Rota. Then it was defined on Lie algebr
as as the operator form of the classical Yang-Baxter equation. Kupershmidt
introduced a more general notion called O-operator (later called relative
Rota-Baxter operator) for arbitrary representation. Rota-Baxter operators
have fruitful applications in mathematical physics. We determine the L-
infty-algebra that characterizes relative Rota-Baxter Lie algebras as Maur
er-Cartan elements. As applications\, first we determine the L-infty-algeb
ra that controls deformations of a relative Rota-Baxter Lie algebra and sh
ow that it is an extension of the dg Lie algebra controlling deformations
of the underlying Lie algebra and representation by the dg Lie algebra con
trolling deformations of the relative Rota-Baxter operator. Then we define
the cohomology of relative Rota-Baxter Lie algebras and relate it to
their infinitesimal deformations. In particular the cohomolgoy of Rota-B
axter Lie algebras and triangular Lie bialgebras are given. Finally we int
roduce the notion of homotopy relative Rota-Baxter operators and show that
the underlying structure is pre-Lie-infinity algebras. This talk is based
on joint works with Chenming Bai\, Li Guo\, Andrey Lazarev and Rong Tang.

DESCRIPTION:Title: Group-valued momentum maps for diffeomorphism groups\nby Tobias
Diez (TU Delft) as part of Global Poisson webinar\n\n\nAbstract\nIn math
ematical physics\, some conserved quantities have a discrete nature\, for
example because they have a topological origin. These conservation laws ca
nnot be captured by the usual momentum map. I will present a generalized n
otion of a momentum map taking values in a Lie group\, which is able to in
clude discrete conversed quantities. It is inspired by the Lu-Weinstein mo
mentum map for Poisson Lie group actions\, but the groups involved do not
necessarily have to be Poisson Lie groups. The most interesting applicatio
ns include momentum maps for diffeomorphism groups which take values in gr
oups of Cheeger-Simons differential characters. As an important example\,
I will show that the Teichmüller space with the Weil-Petersson symplectic
form can be realized as symplectic orbit reduced space.\n

\nby Claudia Scheimbauer (TU München) as part of Global Poisson webinar\
n\n\nAbstract\nDerived algebraic geometry and derived symplectic geometry
in the sense of Pantev-Toen-Vaquié-Vezzosi allows for a reinterpretation/
analog of the classical AKSZ construction for certain $\\sigma$-models. Af
ter recalling this procedure I will explain how it can be extended to give
a fully extended oriented TFT in the sense of Lurie with values in a high
er category whose objects are $n$-shifted symplectic derived stacks and (h

aking mapping stacks with a fixed target building and describes ``semi-cla

roach to general relativity using vielbein with values in a Clifford algeb
ra. This approach allows to simplify computations and in particular define
a hidden $\\mathfrak{sl}(2) \\times \\mathfrak{sl}(2)$ symmetry (and even
affine $\\mathfrak{sl}(4)$ one in the Kaehler case). This formalism all
ows to compute in simple terms the phase space of the theory and the actio
n of the diffeomorphisms on it. The main feature of this situation is that
diffeomorphisms do not form a group\, but a groupoid. We will discuss the
reason for this situation and suggest an analogue of the momentum map. Jo

/a>\nby Marco Zambon (KU Leuven) as part of Global Poisson webinar\n\n\nA
bstract\nLog-symplectic manifolds constitute a class of Poisson manifolds
that in many respects behave like symplectic ones. We address the question
of whether Lagrangian submanifolds and their deformations are as well-beh
aved as in symplectic geometry. Since the case of Lagrangians transversal
to the singular locus is well understood\, we focus on Lagrangian submanif
olds contained in the singular locus. We establish a normal form theorem a
round such submanifolds\, and show that their deformations are governed by
a DGLA. The latter allows to draw geometric consequences: we discuss when
a Lagrangian admits deformations not contained in the singular locus\, an
d we give precise criteria for unobstructedness of first order deformation
s.\n\nThis talk is based on joint work with Stephane Geudens.\n
