Algebraic Stacks

Thursday, 10 August, 2.30-4.00 pm

---------------------------------------------

Venue : Ramanujan Hall

Host: Sudarshan Gurjar

Speaker: Nitin Nitsure, TIFR, Mumbai (retd)

Abstract: I deliver a course of lectures on Algebraic Stacks .The 
tentative plan is to cover the first 100 pages or so of `Champs 
Algebriques' by Laumon and Moret-Bailly, which is the standard reference 
for the subject. Examples, definitions, and statements of results will 
be discussed in detail, and proofs of the main theorems will be 
sketched, focusing on the key ideas.

Topology and Related Topics Seminar 

Thursday, 10 August 2023, 2.30 -3:45  pm

==========================

Venue: Room 215

Host:  Rekha Santhanam

Speaker: Sahin Mandal

Affiliation: IIT Bombay

Title: Vector Bundles and their Classification-1

Abstract: In this talk, we define vector bundles and discuss some examples. We then talk about  Stiefel and Grassmanian manifolds and explain how to construct new vector bundles from the old ones. Later we will talk about the classification of vector bundles in which will see how homotopy maps behave and construct the universal vector bundle.
