DESCRIPTION:Title: Asymptotic stability for the sine-Gordon kink under odd pertu
rbations via super-symmetry\nby Wilhelm Schlag (Yale) as part of Turki
sh Math Society - Distinguished Colloquium Series\n\n\nAbstract\nKinks are
examples of topological solitons in classical field theory. They have bee
n studied for decades\, mostly by methods of complete integrability such a
s the inverse scattering transform. One of the most basic models\, known a
s phi^4\, is not accessible to these techniques and much less is known eve
n about the most basic object of nonzero charge: the kink in one spatial d
imension. I will describe the recent asymptotic analysis with Jonas Luehr
mann (TAMU) of the sine-Gordon evolution of odd data near the kink. While
sine-Gordon is completely integrable\, we do not rely on this property. Th
e talk will present some background on classical fields and the history of
the problem.\n

DESCRIPTION:Title: The propagation of chaos for the multiple optimal stopping pr
oblem\nby Nizar Touzi (Ecole Polytechnique) as part of Turkish Math So
ciety - Distinguished Colloquium Series\n\n\nAbstract\nThe optimal stoppin
g problem of $N$ particles deriven by interacting diffusion processes can
be characterized by a cascade of obstacle Cauchy problems. The limiting pr
oblem is an optimal stopping problem of a McKean-Vlasov diffusion with cri
terion defined as a function of the law of the stopped process. The corres
ponding dynamic programming equation is an obstacle problem on the Wassers
tein space\, and is obtained by means of a general Itô formula for flows
of marginal laws of càdlàg semimartingales. We provide a verification re
sult which characterizes the nature of optimal stopping policies\, highlig
hting the crucial need to randomized stopping. We also introduce a notion
of viscosity solutions on the Wassertsein space which allows to characteri
ze the value function\, and we prove a result of propagation of chaos by a
dapting the monotone scheme convergence argument.\n

DESCRIPTION:Title: Asymmetry in dynamics\nby Amie Wilkinson (U. Chicago) as
part of Turkish Math Society - Distinguished Colloquium Series\n\n\nAbstra
ct\nThe origins of the subject of dynamical systems lie in classical mecha
nics\, in the study of such fundamental problems as the stability of the s
olar system. A theme that traces back to Noether's theorem is that symmet
ries in such physical systems must occur for a reason: for example\, if th
e motion of a system does not depend on position in space\, then there mus
t be a conserved quantity\, such as angular momentum. I will discuss\, i
n the broader contexts of modern dynamics\, how this theme expands and reo
ccurs in beautiful ways: on the one hand\, a typical object has the minimu
m amount of symmetry possible\, and on the other hand\, a little extra sym
metry implies a lot of symmetry\, a phenomenon known as rigidity.\n

DESCRIPTION:Title: Optimal Control\nby Mete Soner (Princeton University) as
part of Turkish Math Society - Distinguished Colloquium Series\n\n\nAbstr
act\nStarting with the moon-landing problem\, the mathematical theory of
optimal control has been fully developed and found numerous applications n
ot only in engineering but also in many subfields of social sciences. In p
articular\, in economics and quantitative finance\, stochastic optimal con
trol has become a central modeling tool\, and is the starting point for m
any modern learning algorithms. The unifying paradigm is decisions under
uncertainty and one imagines that a rational decision maker is guided by a
n appropriate control problem. In this talk\, after describing the struct
ure of the general problem\, I will outline the powerful solution techniqu
e based on dynamic programming. Several applications such as the Kalman f
ilter used in automated machines\, Merton’s problem for optimal investm
ent decisions and the Ellsberg experiment for uncertainty will also be dis
cussed. I will conclude with the new developments and the questions.\n

ian Maneloscu (Stanford) as part of Turkish Math Society - Distinguished C
olloquium Series\n\n\nAbstract\nOver the last forty years\, most progress
in four-dimensional topology came from gauge theory and related invariants
. Khovanov homology is an invariant of knots in R^3 of a different kind: i
ts construction is combinatorial\, and connected to ideas from representat
ion theory. There is hope that it can tell us more about smooth 4-manifold
s\; for example\, Freedman\, Gompf\, Morrison and Walker suggested a strat
egy to disprove the 4D Poincare conjecture using Rasmussen’s invariant f
rom Khovanov homology. It is yet unclear whether their strategy can work.
I will explain a new attempt to pursue it (joint work with Lisa Piccirillo
) and some of the challenges we encountered. I will also review other topo
logical applications of Khovanov homology.\n

DESCRIPTION:Title: Perspectives on automorphic L-functions\nby Yiannis Sake
llaridis (Johns Hopkins U.) as part of Turkish Math Society - Distinguishe
d Colloquium Series\n\n\nAbstract\nL-functions\, which are generalizations
of the Riemann zeta function\, play a role in some of the deepest conject
ures in mathematics. A huge step in their understanding was undertaken in
the late '60s and '70s by Robert Langlands\, who gave a general definition
of automorphic L-functions\, and conjectured that they contain all the L-
functions arising from Galois theory and arithmetic geometry. Still\, the
true nature of these complex-analytic functions which contain crucial arit
hmetic information remained a mystery.\n\nIn this talk\, I will review var
ious incarnations of L-functions associated to number fields or function f
ields\, premised on 2 paradigms: On one hand\, the cohomological interpret
ation of the zeta functions of varieties over finite fields ("the Galois s
ide")\, and\, on the other\, Riemann's interpretation of the zeta function
as a Mellin transform of a theta series ("the automorphic side"). I will
then sketch a correspondence between the two paradigms\, based on joint wo
rk with David Ben-Zvi and Akshay Venkatesh\, based on a conjectural dualit
y between Hamiltonian spaces\, with ramifications that extend into mathema
tical physics.\n

DESCRIPTION:Title: Old-fashioned Machine Learning: Using Diffusion Methods to L

urkish Math Society - Distinguished Colloquium Series\n\n\nAbstract\nMany
datasets consist of complex items that can be reasonably surmised to lie o
n a manifold of much lower dimension than the number of parameters or coor
dinates with which the individual items are acquired. \n\nManifold diffusi
on is an established method\, used successfully to parametrize such datase
ts much more succinctly. The talk describes an enhancement of this method:
when each individual item is itself a complex object\, as is the case in
many applications\, one can model the collection as a fiber bundle\, and b
uild a fiber bundle diffusion operator from which one can gradually learn
properties of the underlying base manifold. This will be illustrated with
applications to morphological evolutionary studies in biology.\n

DESCRIPTION:Title: Geometry of PDEs\nby Tobias Colding (MIT) as part of Tur
kish Math Society - Distinguished Colloquium Series\n\n\nAbstract\nOptimal
geometric structures and the evolution of shapes are governed by partial
differential equations. These same types of equations come up over and ove
r again across many diverse areas in science\, engineering\, and mathemati
cs. The geometric invariance makes the equations canonical and means that
they also describe phenomena seemingly unrelated to geometry. Often the ge
ometry unlocks the structure of the equation and leads to fundamental tool
s in PDE. Conversely\, analysis has played a central role in the developme
nt of geometry. Understanding the equations and their fundamental properti
es requires simultaneous insight into both analysis and geometry and the i
nterplay between the two. \n\nIn this talk\, we will discuss this principl
e for several fundamental equations. We start by seeing how a long-standin
g problem in geometry leads to optimal regularity for viscosity solutions
of a degenerate elliptic PDE\, then turn to using PDE to understand optima
l shapes and geometric evolution.\n

DESCRIPTION:Title: Mass transport\, Kantorovich operators and their ergodic pro
perties\nby Nassif Ghoussoub (UBC) as part of Turkish Math Society - D
istinguished Colloquium Series\n\n\nAbstract\nThe notion of a non-linear K
antorovich operator was motivated by the celebrated duality in the mass tr
ansport problem\, hence the name. In retrospect\, we realized that they -a
nd their iterates- were omnipresent in several branches of analysis\, even
those that are focused on linear Markov operators and their semi-groups s
uch as classical ergodic theory\, potential theory\, and probability theor
y. The Kantorovich operators that appear in these cases\, though non-linea
r\, are all positively 1-homogenous rendering most classical operations on
measures and functions conducted in these theories ``cost-free”. Genera
l Kantorovich operators arise when one assigns "a cost" to such operations
. \n\nKantorovich operators are also Choquet capacities and are the ``lea
st non-linear" extensions of Markov operators\, which make them a relative
ly ``manageable” subclass of non-linear maps. Motivated by the stochasti
c counterpart of Aubry-Mather theory for Lagrangian systems and Fathi-Math
er weak KAM theory\, as well as ergodic optimization of dynamical systems\
, we exhibit the asymptotic properties of general Kantorovich operators.\n

But Euclid’s\ngeometry rests on postulates\, one of which didn’t seem
