DESCRIPTION:Title: Formalisms of gluing Fukaya categories\nby Hiro Lee Tanaka (Texas
State University) as part of Western Hemisphere virtual symplectic semina
r\n\n\nAbstract\nIn the Weinstein setting\, we know that wrapped Fukaya ca
tegories glue\, so it behooves us to understand a general framework that c
aptures the properties of this gluing. After explaining a few approaches o
f how to formalize gluing procedures in the 2-dimensional setting\, we'll
explain why we think a framework inspired by factorization homology seems
most promising to capture the general behavior of local-to-global invarian
ts of Weinstein sectors. Setting up this formalism sheds insights into thi
ngs like the following: (a) We can classify all local-to-global invariants
of 2-dimensional Liouville sectors. (b) We see that the Floer theory of L
agrangian cobordisms in R^oo recovers the higher K theory of the integers.
(We have been unable to compute this higher K theory for decades\, and a
computation would yield powerful results in arithmetic.) (c) Wrapped Floer
theory can shed insight into higher homotopy groups of Liouville embeddin
g spaces.\n

DESCRIPTION:Title: Homological mirror symmetry for elliptic Hopf surfaces\nby Abigai
l Ward (Harvard) as part of Western Hemisphere virtual symplectic seminar\
n\n\nAbstract\nOne can produce non-Kähler complex surfaces by performing
logarithmic transformations on projective elliptic surfaces\; for example\
, elliptic Hopf surfaces (including the classical Hopf surface $S^1 \\time
s S^3$) can be obtained by performing such operations to the product of th
e projective plane with an elliptic curve. In situations where the origina
l surface has a mirror symplectic space\, one can ask if there is a "mirro
r operation" to the logarithmic transformation\, i.e. a way of producing a
mirror to the logarithmically transformed surface from the original mirro
r space. We will discuss an answer to this question in the case of ellipti
c Hopf surfaces. For each such surface $S$\, we will produce a mirror "non
-algebraic Landau-Ginzburg model" with an associated Fukaya category. We w
ill relate objects of this Fukaya category to coherent analytic sheaves on
$S$.\n

n this talk\, we will explain how to construct Liouville manifolds which h

In particular\, we construct an exotic symplectic structure on Euclidean
space which is not distinguished by traditional Floer homology invariants.
Instead\, it is detected by a module spectrum for complex K-theory\, buil
t as a variant of Cohen-Jones-Segal’s Floer homotopy type. The proof inv

We upgrade to a full Z-grading\, and in combination with the domain depe
ndent methods introduced by Farris in his thesis\, make use of the direct
limits for filtered ECH established in Hutchings-Taubes proof of the Arnol
d-Chord conjecture to extend the Morse-Bott methods for prequantization bu

prequantization bundle over a Riemann surface is isomorphic to the exteri
or algebra of the homology of this base. We comment on future work\, whi
ch relates the U map in ECH to Gromov-Witten invariants of the base\, perm

DESCRIPTION:Title: Generalizations of Hodge-de-Rham degeneration for Fukaya categories\nby Semon Rezchikov (Columbia) as part of Western Hemisphere virtual sy
mplectic seminar\n\n\nAbstract\nHodge theory shows that the Hodge-de-Rham
spectral sequence associated to a compact Kahler manifold degenerates. Kal
edin showed that the non-commutative Hodge-de-Rham spectral sequence assoc
iated to a smooth proper dg-category over a field of characteristic zero d
egenerates as well. When the category is just smooth or just proper\, Kont
sevich conjectured that certain weaker statements\, which are true for smo
oth or proper varieties\, should continue to hold in the categorical setti
ng. Recently\, counterexamples to Kontsevich's conjectures were found by E
fimov. I will discuss the background to this story\, and then I will expla
in why the conjectures of Kontsevich do hold\, for analytic reasons\, when
the category is a Fukaya category. The argument suggests interesting dire

DESCRIPTION:Title: An annular filtration on Sarkar-Seed-Szabó's spectral sequence\n
by Melissa Zhang (University of Georgia) as part of Western Hemisphere vir
tual symplectic seminar\n\n\nAbstract\nKhovanov homology is a combinatoria
l invariant of links in the three-sphere borne from structures in represen
tation theory. Nevertheless\, there are many spectral sequences relating K
hovanov homology to geometrically-defined invariants\, such as Ozsváth-Sz
abó's Heegaard Floer homology. Seidel-Smith defined its geometric counter
part\, symplectic Khovanov homology\, which Abouzaid-Smith showed is indee
d isomorphic to combinatorial Khovanov homology over characteristic 0. Ins
pired by symplectic Khovanov homology's O(2) action\, Sarkar-Seed-Szabó e
xtended Szabó's geometric spectral sequence\, which is a combinatorial sp
ectral sequence conjectured to be isomorphic to Ozsváth-Szabó's spectral
sequence (from the Khovanov homology of a knot to the Heegaard Floer homo
logy of the branched double cover of its mirror knot). A bifiltered versio
n of this complex admits a family of Rasmussen-type link invariants.\n\nIn
joint work with Linh Truong\, we show that for links in a solid torus (i.
e. annular links)\, Sarkar-Seed-Szabó's complex admits third filtration.
This annular filtration allows us to define a 2-parameter family of annula
r concordance invariants s_{r\,t} analogous to Grigsby-Licata-Wehrli's ann
ular Rasmussen invariants d_t (from annular Khovanov-Lee theory). The two
families share many properties\, including applications to 3D contact geom
etry and smooth knot concordance.\n

DESCRIPTION:Title: Lifting cobordisms and Kontsevich-type recursions for counts of real
curves\nby Xujia Chen (Stony Brook University) as part of Western Hemi
sphere virtual symplectic seminar\n\n\nAbstract\nKontsevich's recursion\,
proved by Ruan-Tian in the early 90s\, is a recursion formula for genus 0
Gromov-Witten invariants. For symplectic fourfolds and sixfolds with a rea
l structure (i.e. an anti-symplectic involution\, analogue of the usual co
njugation map on C^n)\, signed invariant counts of real rational pseudo-ho
lomorphic curves were defined by Welschinger in 2003. In 2006-07\, Solomon
re-interpreted Welschinger's invariants\, proposed Kontsevich-type recurs
ion formulas for them\, and suggested a potential adaptation of the proof
in the complex case for confirming them. For many symplectic fourfolds and
sixfolds\, these recursions determine all invariants from basic inputs. W
e establish Solomon's recursions by a different approach: lifting cobordis
ms from the moduli spaces of real domains to the moduli space of real maps
and incorporating the wall-crossing corrections from the walls obstructin
g relative-orientability.\n

first produce flexible subdomains of $T^*S^n$\, which in high-dimensions
yield exotic Weinstein presentations for $T^*S^n$ as the standard ball wit
h a single handle attached along an exotic Legendrian knot. The algebraic
side of the story for the wrapped Fukaya category is closely connected to
a result of Thomason in algebraic K-theory. Then we discuss joint work wit
h Z. Sylvan that associates to every finite collection of prime integers a
(non-flexible) Weinstein subdomain of $T^*S^n$ whose Fukaya category is l
ocalized at those primes and show that the Fukaya category of any Weinstei

nby Daniel Álvarez-Gavela (Princeton) as part of Western Hemisphere virtu

y of spaces. These connections have opened up as a consequence of the rece
nt existence result for (twisted) generating functions due to Abouzaid\, C
ourte\, Guillermou and Kragh. In work in progress joint with Abouzaid\, Co
urte and Kragh we find that a certain geometric description of the splitti
ng map for the algebraic K-theory of a point due to Waldhausen and Bökste
dt gives a new restriction on the framed bordism class of nearby Lagrangia
ns. In particular I will show that if L is any Lagrangian homotopy sphere
in the cotangent bundle of the standard sphere\, then the connected sum of
L with itself bounds a parallelizable manifold. This extends known constr
aints for the possible class of L in the group of homotopy spheres modulo
those which bound a parallelizable manifold. I will also touch on joint wo

multiple cut operation on a symplectic manifold produces a collection of c

what happens to curve count-based invariants when a collection of cuts is

algebra of a Lagrangian submanifold that is contained in the complement of
relative divisors. The ordinary Fukaya algebra in the unbroken manifold i
s homotopy equivalent to a `broken Fukaya algebra' whose structure maps co
unt `broken disks' associated to rigid tropical graphs. Via a further dege
neration\, the broken Fukaya algebra is homotopy equivalent to a `tropical
Fukaya algebra' whose structure maps are sums of products over vertices o

nA landmark result\, due to McDuff and Schlenk\, asserts that in determini
ng when a four-dimensional symplectic ellipsoid can be symplectically embe
dded into a four-dimensional ball\, the answer is given by an “infinite
staircase” determined by the odd-index Fibonacci numbers and the Golden
Mean. There has recently been considerable interest in better understandin
g this phenomenon for more general embedding problems. I will explain a t
heorem showing that for any four-dimensional convex toric domain of finite
type\, if an infinite staircase occurs\, then its singular points must ac
cumulate at a unique point\, characterized by an explicit quadratic equati
on. I will then explain how to apply this theorem to prove that when the
target is a rational ellipsoid\, there is an infinite staircase in precise
ly three cases -- when the target has "eccentricity" 1\, 2\, or 3/2\; inte
restingly\, in each of these cases\, the corresponding embeddings can be c

DESCRIPTION:Title: SO(3)-instantons and the Atiyah-Floer Conjecture\nby Aliakbar Da
emi (WUSTL) as part of Western Hemisphere virtual symplectic seminar\n\n\n
Abstract\nA useful tool to study a 3-manifold is the space of representati
ons of its fundamental group into a Lie group. Any 3-manifold can be decom
posed as the union of two handlebodies. Thus representations of the 3-mani
fold group into a Lie group can be obtained by intersecting representation
varieties of the two handlebodies. Casson utilized this observation to de
fine his celebrated invariant. Later Taubes introduced an alternative appr
oach to define Casson invariant using more geometrical objects. By buildin
g on Taubes' work\, Floer refined Casson invariant into a 3-manifold invar
iant which is known as instanton Floer homology. The Atiyah-Floer conjectu
re states that Casson's original approach can be also used to define a gra
ded vector space and the resulting invariant of 3-manifolds is isomorphic
to instanton Floer homology. In this talk\, I will discuss a variation of
the Atiyah-Floer conjecture\, which states that framed Floer homology (def
ined by Kronheimer and Mrowka) is isomorphic to symplectic framed Floer ho
mology (defined by Wehrheim and Woodward). I will explain how the closed-o
pen string map is related to framed Floer homology. Finally I comment on h
ow earlier works of Seidel and Smith might provide useful computational to
ols for framed Floer homology. This talk is based on a joint work with Ken
ji Fukaya and Maksim Lipyanskyi.\n

DESCRIPTION:Title: Microlocal sheaf categories and the J-homomorphism\nby Xin Jin (
Boston College) as part of Western Hemisphere virtual symplectic seminar\n
\n\nAbstract\nThe theory of microlocal sheaves\, developed by Kashiwara--S
chapira\, has found many applications in the study of symplectic topology.
For a smooth Lagrangian L in a cotangent bundle of a smooth manifold and
a commutative ring spectrum k\, one can associate a sheaf of microlocal ca
tegories\, which is locally constant with fiber equivalent to Mod(k). It a
dmits a classifying map L--->BPic(k). We will show that the classifying ma
p factors through the Gauss map L--->U/O and the delooping of the J-homomo
rphism U/O--->BPic(S)\, where S is the sphere spectrum. As an application\
, combining with previous results of Guillermou\, we show that if L is a c
ompact smooth exact Lagrangian\, then the classifying map is homotopically
trivial\, recovering a result of Abouzaid--Kragh.\n

DESCRIPTION:Title: Symplectic annular Khovanov homology\nby Cheuk Yu Mak (Cambridge
) as part of Western Hemisphere virtual symplectic seminar\n\n\nAbstract\n
Annular Khovanov homology is an invariant of annular links (links in a sol
id torus) introduced by Asaeda-Przytycki-Sikora as an analogue of Khovanov
homology for links. Auroux-Grigsby-Wehrli showed that the first piece of
the annular Khovanov homology can be identified with the Hochschild homolo
gy of the Fukaya-Seidel category of A_n Milnor fibers with coefficients in
braid bimodules. In this talk\, we will introduce a symplectic version of
annular Khovanov homology using Hochschild homology of the Fukaya-Seidel
category of more general type A nilpotent slices. Building on the work of
Abouzaid-Smith and Beliakova-Putyra-Wehrli\, we show that the symplectic v
ersion is isomorphic to the ordinary version. Finally\, we will explain ho
w to derive a spectral sequence from the symplectic annular Khovanov homol
ogy to the symplectic Khovanov homology directly using symplectic geometry
. This is based on a joint work with Ivan Smith.\n

DESCRIPTION:Title: The singular Weinstein conjecture\nby Eva Miranda (Universitat P
olitècnica de Catalunya) as part of Western Hemisphere virtual symplectic
seminar\n\n\nAbstract\nThe purpose of this talk is to present some recent
results concerning Reeb dynamics on a $b^m$-contact manifolds. b-Contact
manifolds (and more generally b^m´-contact manifolds) are the odd-dimensi
onal counterpart to $b^m$-symplectic manifolds which have been a center of
attention in Poisson Geometry. The study of $b^m$-Reeb dynamics is motiva
ted by well-known problems in fluid dynamics (Beltrami fields) and celesti
al mechanics\, where those geometric structures naturally appear. \n\nThe
first part of the talk will focus on the singular Weinstein conjecture fo
llowing https://arxiv.org/abs/2005.09568 (joint work with Cédric Oms). W
e prove that in dimension 3 there are always infinite periodic orbits on t
he critical set (if compact). In particular\, we will prove that the dynam
ics on positive energy level-sets in the restricted planar circular three-
body problem are described by the Reeb vector field of a $b^3$-contact for
m that admits an infinite number of periodic orbits at the critical set.
This investigation goes hand-in-hand with the Weinstein conjecture on non-
compact manifolds having compact ends of convex type. In particular\, we e
xtend Hofer's arguments to open overtwisted contact manifolds that are $\\
R^+$-invariant in the open ends\, obtaining as a corollary the existence o
f periodic $b^m$-Reeb orbits away from the critical set.\n\nAt the end of
the talk\, we will focus on singular Reeb orbits (joint work with Cédric
Oms and Daniel Peralta-Salas). Inspired by Poincaré's orbits going to inf
inity in the (restricted) three-body problem\, we investigate the existenc
e of singular Reeb orbits emanating from/going to the critical set and we
prove their existence for generic Melrose b-contact structures. In the pro
of\, we use the correspondence between b-Beltrami vector fields and b-cont
act structures.\n

Abstract\nRelative symplectic cohomology\, constructed by U.Varolgunes\, p
rovides a useful tool to study topological and dynamical properties of clo
sed subsets in a symplectic manifold. I will discuss several computational
aspects about it\, with a focus on index bounded Liouville domains in Cal
abi-Yau manifolds. In particular\, a spectral sequence will be defined in
this case. If time permits\, some thought of the homologically index bonde
d case will also be explained.\n
