Title: Stabilization of heat equation by the backstepping method - I.
Abstract: This presentation considers the one-dimensional heat equation
with Dirichlet boundary conditions. We will study how we can make an
unstable (heat) system stable by means of some external input (control
function) through the boundary using the backstepping method. Our main
goal of this talk is to understand the backstepping method for the
simple 1-d heat case.

Lecture series on Hodge Theory
Wednesday and Thursday
6 and 7 September, 11:30 am – 1.00 pm
------------------------------------------------
Venue: Ramanujan Hall
Host: Sudarshan Gurjar
Speaker: V. Srinivas
Affiliation: IIT Bombay
Title: Introduction to Hodge Theory
Abstract: These are part of an ongoing series of lectures on the basics of Hodge theory. The next two lectures will finish the proof of the de Rham theorem, via sheaf cohomology, and if time permits, a beginning will be made on some linear algebra needed for the Hodge theory, as in Chapter 1 of Huybrechts' book.

Title: Some topological aspects of Riemannian geometry
Abstract: In this talk, I plan to prove the Cartan-Hadamard theorem which talks about the universal cover of a complete Riemannian manifold with non-positive sectional curvature. We shall also see a proof of Myer's theorem about the fundamental group of a complete Riemannian manifold with positive sectional curvature.
