Speaker: Nguyen Quang Khai

Time: 9h-11h, Wednesday, October 21, 2020.

Location: Room 509, A6

Abstratc: The étale cohomology groups of an algebraic variety or scheme are algebraic analogues of the usual cohomology groups with finite coefficients of a topological space, introduced by Grothendieck in order to prove the Weil conjectures. In this seminar, we introduce the notion of etale cohomology and give its relation with Galois cohomology.
