4:00pm [4:00pm] Prof. A.J. Parameswaran, TIFR, Mumbai
Description:
Prof. A.J. Parameswaran from TIFR, Mumbai will give a seminar this Friday at 4:00 pm in Ramanujan Hall. Title: Topology by Bundles. Abstract: Beginning with Wyle's theorem that a bundle induced by the Universal cover is finite (satisfies a polynomial) and its converse by Nori that finite/essentially finite bundles are induced from "coverings/finite principal bundles". We will revisit the etale fundamental group of Grothendieck and the fundamental group scheme by Nori. Later we will glance through other associated group constructions using Tannakian techniques using bundles.
