DESCRIPTION:Title:
Harish-Chandra tempered representations and homogeneous spaces\nby Pro
f. Yves Benoist (University of Paris-Saclay) as part of TMC Distinguished
Lecture Series\n\n\nAbstract\nIn the seventies Harish-Chandra introduced t
he tempered representations of a semisimple real Lie group G as those that
occur in the analog on G of the Fourier-Plancherel formula. Nowadays\, th
ose representations are ubiquitous.\n\nIn this talk we will recall their d
efinition and properties and we will answer the following question:\n\nFor
which connected subgroup H\, does the analog on G/H of the Fourier-Planch
erel formula involves only tempered representations?\n

DESCRIPTION:Title:
3264 Conics in a Second\nby Prof. Bernd Sturmfels (Max Planck Institut
e\, Leipzig and University of California\, Berkeley) as part of TMC Distin
guished Lecture Series\n\n\nAbstract\nThis seminar spans a bridge between
19th century geometry to 21st century computing. We start with a classical
theme that was featured in the January 2020 issue of the Notices of the A
merican Mathematical Society\, namely the 3264 conics that are tangent to
five given conics in the plane. We discuss the computation of these conics
\, by solving a system of polynomial equations with numerical methods that
are fast and reliable. In our discussion we will focus on the role of app
lied algebraic geometry in statistics and optimization\, starting from the
role of linear spaces of symmetric matrices (LSSM) for Gaussian models an
d semidefinite programming.\n

DESCRIPTION:Title:
Stability\, non-approximate groups\, and high dimensional expanders\nb
y Prof. Alex Lubotzky (Einstein Institute of Mathematics\, Hebrew Universi
ty) as part of TMC Distinguished Lecture Series\n\n\nAbstract\nSeveral wel
l-known open questions (such as: are all groups sofic or hyperlinear?) hav
e a common form: can all groups be approximated by asymptotic homomorphism
s into the symmetric groups Sym(n) (in the sofic case) or the unitary grou
ps U(n) (in the hyperlinear case)?\nIn the case of U(n)\, the question can
be asked with respect to different metrics and norms. We answer\, for the
first time\, one of these versions\, showing that there exist finitely pr
esented groups which are not approximated by U(n) with respect to the Frob
enius (=L2) norm.\nThe strategy is via the notion of 'stability': some hi
gher dimensional cohomology vanishing phenomena is proven to imply stabili
ty and using higher dimensional expanders\, it is shown that some non-resi
dually finite groups (central extensions of some lattices in p-adic Lie gr
oups) are Frobenious stable and hence cannot be Frobenius approximated.\nA
ll notions will be explained. Joint work with M. De Chiffre\, L. Glebsky a
nd A. Thom.\n

DESCRIPTION:Title:
Pandemics and paradox\nby Prof. Scott Sheffield (Massachusetts Institu
te of Technology) as part of TMC Distinguished Lecture Series\n\n\nAbstrac
t\nIn one of the simplest epidemic models\, one lets p_n denote the number
of new infections during week n and assumes that (during the early stages
of the epidemic) p_{n+1} = R_0 p_n c_n where c_n measures the “frac
tion of usual contact” that takes place between people during the nth we
ek. Within this simplistic model\, intermittent strategies (taking c_n s
mall some weeks and large other weeks) lead to lower infection rates than
consistent strategies with the same total amount of contact.\n\nBut what h
appens in more life-like models (such as SEIR and its network-based varian
ts)? What factors cause intermittent strategies to outperform consistent s
trategies? What changes when there are multiple subpopulations with differ
ent controls? I will discuss some work with public health researchers that
explores these questions for simple examples. Some of the models are coun
terintuitive: the strategy one expects to be “best possible” turns out
to be “worst possible” and vice versa.\n

DESCRIPTION:Title: Extremal singularities in prime characteristic\nby Prof. Karen E. Smi
th (University of Michigan) as part of TMC Distinguished Lecture Series\n\
n\nAbstract\nWhat is the most singular possible singularity? What can we s
ay about its geometric and algebraic properties? This seemingly naive ques
tion has a sensible answer in characteristic p. The "F-pure threshold\," w
hich is an analog of the log canonical threshold\, can be used to "measure
" how bad a singularity is. The F-pure threshold is a numerical invariant
of a point on (say) a hypersurface---a positive rational number that is 1
at any smooth point (or more generally\, any F-pure point) but less than o
ne in general\, with "more singular" points having smaller F-pure threshol
ds. We explain a recently proved lower bound on the F-pure threshold in te
rms of the multiplicity of the singularity. We also show that there is a n
ice class of hypersurfaces---which we call "Extremal hypersurfaces"---for
which this bound is achieved. These have very nice (extreme!) geometric pr
operties. For example\, the affine cone over a non Frobenius split cubic s
urface of characteristic two is one example of an "extremal singularity".
Geometrically\, these are the only cubic surfaces with the property that *
every* triple of coplanar lines on the surface meets in a single point (ra
ther than a "triangle" as expected)---a very extreme property indeed.\n\nP

DESCRIPTION:Title: On Brumer-Stark units and Hilbert's 12th problem\nby Prof. Samit Dasg
upta & Prof. Mahesh Kakde (Duke University & Indian Institute of Science\,
respectively) as part of TMC Distinguished Lecture Series\n\n\nAbstract\n
Class field theory describes abelian extensions of a number field in terms
of data intrinsic to the field. Hilbert’s 12th problem\, or explicit cl
ass field theory\, goes further and asks for explicit generators of abelia
n extensions of a number field as values of analytic functions. Stark’s
conjectures provide a different perspective by postulating existence of sp
ecial elements\, now called Stark units\, related to leading terms of L-fu
nctions at s=0 and generating abelian extensions of a number field. In thi
s talk we will first review classical results on explicit class field theo
ry for the field of rational numbers and imaginary quadratic fields. Next
we review Stickelberger’s theorem on annihilation of class groups of abe
lian extensions of the field of rational numbers. Brumer-Stark conjecture
is an analogue of Stickelberger’s theorem for arbitrary totally real fie
lds. We will see the statement of this conjecture along with its refinemen
ts and our results towards them. We prove these conjectures away from p=2
Brumer-Stark conjecture gives existence of special elements called Brumer
-Stark units. These generate abelian extensions of a totally real number f
ield. A conjecture by one of us gives p-adic analytic formulae for Brumer-
Stark units. We will discuss this conjecture. Our recent work proves this
conjecture away from p=2 thus providing a p-adic analytic solution to Hilb
ert’s 12th problem for totally real number fields. We will end with a br
ief sketch of our proofs.\n

DESCRIPTION:Title: $G_a$-actions and their applications\nby Prof. Neena Gupta (Indian St
atistical Institute\, Kolkata) as part of TMC Distinguished Lecture Series
\n\n\nAbstract\nLet $k$ be an algebraically closed field\, $V$ be an affin
e $k$-variety and $A$ be its coordinate ring. A $G_a$-action on $V$ is an
algebraic group action of the additive group $(k\, +)$ on $V$. A $G_a$-ac
tion on $V$ gives rise to a certain ring homomorphism from $A$ to the poly
nomial ring $A[T]$ called an exponential map on the ring $A$. When $k$ is
of characteristic zero\, $G_a$-actions or exponential maps is convenientl
y studied through the concept of locally nilpotent derivations. Techniques
from locally nilpotent derivations and exponential maps have provided cru
cial breakthroughs in solving some of the major challenging problems on po
lynomial rings. In this talk\, we discuss a few examples of these developm
ents.\n

DESCRIPTION:Title: Finite quotients of 3-manifold groups\nby Prof. Melanie Matchett Wood
(Harvard University) as part of TMC Distinguished Lecture Series\n\n\nAbs
tract\nFor any finite group G\, it is easy to see there exists a compact\,
oriented 3 dimensional manifold M with G as a quotient of the fundamental
group of M. However\, we can ask more detailed questions about the possi
ble finite quotients of 3-manifold groups\, e.g. for G and H finite groups
\, does there exist a 3-manifold group with G as a quotient but not H as a
quotient? We answer all such questions. To prove non-existence\, we pro
ve new parity properties of the fundamental groups of 3-manifolds. To pro
ve existence of 3-manifolds with certain finite quotients but not others\,
we use a probabilistic method\, by first proving a formula for the distri
bution of the fundamental group of a random 3-manifold\, in the sense of D
unfield-Thurston. This is joint work with Will Sawin.\n

DESCRIPTION:Title: Graphical Designs\nby Prof. Rekha R. Thomas (University of Washington
) as part of TMC Distinguished Lecture Series\n\n\nAbstract\nA graphical d
esign on an undirected graph is a quadrature rule in the following sense:
Given an eigenbasis of the graph Laplacian\, a design is a collection of v
ertices of the graph (with weights) so that the weighted average of a coll
ection of eigenvectors on this subset equals the weighted average on the f
ull set of vertices. Depending on which eigenvectors are to be averaged\,
and requirements on the weights\, one obtains different types of designs.
Designs can be computed via linear and integer programming. In this talk I
will show that positively weighted designs can be organized on the faces
of a polytope\, and using this connection\, we compute optimal designs in
several graph families. Joint work with Catherine Babecki.\n

DESCRIPTION:Title: Asymmetry in dynamics\nby Prof. Amie Wilkinson (University of Chicago
) as part of TMC Distinguished Lecture Series\n\n\nAbstract\nWe shall init
ially discuss what symmetries mean in the context of dynamical systems of
different flavors: complex analytic\, Hamiltonian\, or smooth. We shall th
en discuss progress towards a resolution of a conjecture of Smale: a gener
ic smooth dynamical system has only trivial symmetries.\n
