Title: A duality for Selmer groups
Time: 14:30 - 15:30, Wednesday, October 17, 2018.
Venue: Ramanujan Hall, Department of Mathematics
Abstract: Selmer group is an important object of study in number theory.
We will discuss a twisting result in the setting of so called
"non-commutative" Iwasawa theory. We will further use this to deduce a
duality result for certain Selmer groups. (This talk is based on joint
works with T. Ochiai, G. Zabradi and S. Shekhar.

Title: An overview of the theory of Hypocoercivity.
Abstract: In this talk, we attempt to give a brief introduction to the
theory of Hypocoercivity which has become an indispensable tool in the
study of relaxation to equilibrium states for mathematical models arising
in statistical physics. The essential ideas behind this theory will be
motivated via simple examples. The role of certain functional inequalities
while deriving explicit rates of convergence will be made precise during
this talk. This talk concludes by addressing a certain degenerate kinetic
Fokker-Planck equation. Incidentally, the study of the trend to
equilibrium for this degenerate model finds link to the acclaimed
Geometric Condition from the theory of control for wave propagation.
