DESCRIPTION:Title: Harish-Chandra tempered representations and homogeneous spaces\
nby Prof. Yves Benoist (University of Paris-Saclay) as part of TMC Disting
uished Lecture Series\n\n\nAbstract\nIn the seventies Harish-Chandra intro
duced the tempered representations of a semisimple real Lie group G as tho
se that occur in the analog on G of the Fourier-Plancherel formula. Nowada
ys\, those representations are ubiquitous.\n\nIn this talk we will recall
their definition and properties and we will answer the following question:
\n\nFor which connected subgroup H\, does the analog on G/H of the Fourier
-Plancherel formula involves only tempered representations?\n

DESCRIPTION:Title: 3264 Conics in a Second\nby Prof. Bernd Sturmfels (Max Planck I
nstitute\, Leipzig and University of California\, Berkeley) as part of TMC
Distinguished Lecture Series\n\n\nAbstract\nThis seminar spans a bridge b
etween 19th century geometry to 21st century computing. We start with a cl
assical theme that was featured in the January 2020 issue of the Notices o
f the American Mathematical Society\, namely the 3264 conics that are tang
ent to five given conics in the plane. We discuss the computation of these
conics\, by solving a system of polynomial equations with numerical metho
ds that are fast and reliable. In our discussion we will focus on the role
of applied algebraic geometry in statistics and optimization\, starting f
rom the role of linear spaces of symmetric matrices (LSSM) for Gaussian mo
dels and semidefinite programming.\n

DESCRIPTION:Title: Stability\, non-approximate groups\, and high dimensional expanders
\nby Prof. Alex Lubotzky (Einstein Institute of Mathematics\, Hebrew U
niversity) as part of TMC Distinguished Lecture Series\n\n\nAbstract\nSeve
ral well-known open questions (such as: are all groups sofic or hyperlinea
r?) have a common form: can all groups be approximated by asymptotic homom
orphisms into the symmetric groups Sym(n) (in the sofic case) or the unita
ry groups U(n) (in the hyperlinear case)?\nIn the case of U(n)\, the quest
ion can be asked with respect to different metrics and norms. We answer\,
for the first time\, one of these versions\, showing that there exist fini
tely presented groups which are not approximated by U(n) with respect to t
he Frobenius (=L2) norm.\nThe strategy is via the notion of 'stability':
some higher dimensional cohomology vanishing phenomena is proven to imply
stability and using higher dimensional expanders\, it is shown that some n
on-residually finite groups (central extensions of some lattices in p-adic
Lie groups) are Frobenious stable and hence cannot be Frobenius approxima
ted.\nAll notions will be explained. Joint work with M. De Chiffre\, L. Gl
ebsky and A. Thom.\n

DESCRIPTION:Title: Pandemics and paradox\nby Prof. Scott Sheffield (Massachusetts
Institute of Technology) as part of TMC Distinguished Lecture Series\n\n\n
Abstract\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
“fraction of usual contact” that takes place between people during the
nth week. Within this simplistic model\, intermittent strategies (taking
c_n small some weeks and large other weeks) lead to lower infection rate
s than consistent strategies with the same total amount of contact.\n\nBut
what happens in more life-like models (such as SEIR and its network-based
variants)? What factors cause intermittent strategies to outperform consi
stent strategies? What changes when there are multiple subpopulations with
different controls? I will discuss some work with public health researche
rs that explores these questions for simple examples. Some of the models a
re counterintuitive: the strategy one expects to be “best possible” tu
rns out to be “worst possible” and vice versa.\n

DESCRIPTION:Title: Extremal singularities in prime characteristic\nby Prof. Karen
E. Smith (University of Michigan) as part of TMC Distinguished Lecture Se
ries\n\n\nAbstract\nWhat is the most singular possible singularity? What c
an we say about its geometric and algebraic properties? This seemingly nai
ve question has a sensible answer in characteristic p. The "F-pure thresho
ld\," which 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 inv
ariant of a point on (say) a hypersurface---a positive rational number tha
t is 1 at any smooth point (or more generally\, any F-pure point) but less
than one in general\, with "more singular" points having smaller F-pure t
hresholds. We explain a recently proved lower bound on the F-pure threshol
d in terms of the multiplicity of the singularity. We also show that there
is a nice class of hypersurfaces---which we call "Extremal hypersurfaces"
---for which this bound is achieved. These have very nice (extreme!) geome
tric properties. For example\, the affine cone over a non Frobenius split
cubic surface of characteristic two is one example of an "extremal singula
rity". Geometrically\, these are the only cubic surfaces with the property
that *every* triple of coplanar lines on the surface meets in a single po
int (rather than a "triangle" as expected)---a very extreme property indee
d.\n\nProf. Karen E. Smith will deliver a live talk on April 08\, 2021 at

DESCRIPTION:Title: On Brumer-Stark units and Hilbert's 12th problem\nby Prof. Sam
it Dasgupta & Prof. Mahesh Kakde (Duke University & Indian Institute of Sc
ience\, respectively) as part of TMC Distinguished Lecture Series\n\n\nAbs
tract\nClass field theory describes abelian extensions of a number field i
n terms of data intrinsic to the field. Hilbert’s 12th problem\, or expl
icit class field theory\, goes further and asks for explicit generators of
abelian extensions of a number field as values of analytic functions. Sta
rk’s conjectures provide a different perspective by postulating existenc
e of special elements\, now called Stark units\, related to leading terms
of L-functions at s=0 and generating abelian extensions of a number field.
In this talk we will first review classical results on explicit class fie
ld theory for the field of rational numbers and imaginary quadratic fields
. Next we review Stickelberger’s theorem on annihilation of class groups
of abelian extensions of the field of rational numbers. Brumer-Stark conj
ecture is an analogue of Stickelberger’s theorem for arbitrary totally r
eal fields. We will see the statement of this conjecture along with its re
finements and our results towards them. We prove these conjectures away fr
om p=2 Brumer-Stark conjecture gives existence of special elements called
Brumer-Stark units. These generate abelian extensions of a totally real n
umber field. A conjecture by one of us gives p-adic analytic formulae for
Brumer-Stark units. We will discuss this conjecture. Our recent work prove
s this conjecture away from p=2 thus providing a p-adic analytic solution
to Hilbert’s 12th problem for totally real number fields. We will end wi
th a brief sketch of our proofs.\n

DESCRIPTION:Title: $G_a$-actions and their applications\nby Prof. Neena Gupta (In
dian Statistical Institute\, Kolkata) as part of TMC Distinguished Lecture
Series\n\n\nAbstract\nLet $k$ be an algebraically closed field\, $V$ be a
n affine $k$-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$-action on $V$ gives rise to a certain ring homomorphism from $A$ to t
he polynomial ring $A[T]$ called an exponential map on the ring $A$. When
$k$ is of characteristic zero\, $G_a$-actions or exponential maps is conv
eniently studied through the concept of locally nilpotent derivations. Tec
hniques from locally nilpotent derivations and exponential maps have provi
ded crucial breakthroughs in solving some of the major challenging problem
s on polynomial rings. In this talk\, we discuss a few examples of these d
evelopments.\n

DESCRIPTION:Title: Finite quotients of 3-manifold groups\nby Prof. Melanie Matche
tt Wood (Harvard University) as part of TMC Distinguished Lecture Series\n
\n\nAbstract\nFor any finite group G\, it is easy to see there exists a co
mpact\, oriented 3 dimensional manifold M with G as a quotient of the fund
amental group of M. However\, we can ask more detailed questions about th
e possible 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 prove new parity properties of the fundamental groups of 3-manifolds.
To prove existence of 3-manifolds with certain finite quotients but not o
thers\, we use a probabilistic method\, by first proving a formula for the
distribution of the fundamental group of a random 3-manifold\, in the sen
se of Dunfield-Thurston. This is joint work with Will Sawin.\n

DESCRIPTION:Title: Graphical Designs\nby Prof. Rekha R. Thomas (University of Was
hington) as part of TMC Distinguished Lecture Series\n\n\nAbstract\nA grap
hical design on an undirected graph is a quadrature rule in the following
sense: Given an eigenbasis of the graph Laplacian\, a design is a collecti
on of vertices of the graph (with weights) so that the weighted average of
a collection of eigenvectors on this subset equals the weighted average o
n the full set of vertices. Depending on which eigenvectors are to be aver
aged\, and requirements on the weights\, one obtains different types of de
signs. 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 desi
gns 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 sha
ll initially discuss what symmetries mean in the context of dynamical syst
ems of different flavors: complex analytic\, Hamiltonian\, or smooth. We s
hall then discuss progress towards a resolution of a conjecture of Smale:
a generic smooth dynamical system has only trivial symmetries.\n

DESCRIPTION:Title: On the tensor product of representations of classical groups\n
by Prof. Dipendra Prasad (Indian Institute of Technology Bombay) as part o
f TMC Distinguished Lecture Series\n\n\nAbstract\nAfter giving a general i
ntroduction to the representation theory of GL(n\,C) and other classical g
roups\, I will focus attention on Dibyendu Biswas's thesis work around the
question of tensor product of representations of GL(n\,C) and other class
ical groups.\n
