Abstract: Holomorphic vector bundles on compact Riemann surfaces and its
other avatar, namely algebraic vector bundles on smooth, complex
projective curves has a long and rich history with important contributions
by the Indian Algebraic Geometry school. I will introduce this subject
with special focus on bundles which come from representations of the
fundamental group of the surface. Much of the talk will be accessible to
Ph.D students.

Title: Initial ideals and applications
Abstract: In the previous talk, we saw that given an ideal I in a
polynomial ring R, the monomials not in the initial ideal of I form a
basis of R/I. In this talk, we will see further examples of how to use the
initial ideal of I to get more information about I (or R/I).

Title: Control of infinite dimensional linear systems
Speaker: Debanjana Mitra
Abstract: We continue the discussion of the asymptotic behavior of a C_0
semigroup. Then, the different notions of controllability of a linear
system in infinite dimension will be introduced in an abstract set up. For
example, we study the heat equation in details.
