Title : Grothendieck's theorem on algebraic de Rham cohomology of
varieties
Speaker: Saurav Bhaumik
Time & Date: 45pm, Tuesday 16th April.
Venue: Ramanujan Hall.
Abstract: Let X be a smooth scheme of finite type over C, and let X' be
the corresponding complex analytic variety. Grothendieck proved that the
complex cohomologies H^q(X') can be calculated as the hypercohomologyes of
the algebraic de Rham complex on X. We will present Grothendieck's proof.

 Description:
 Popular Talk in Mathematics.
Speaker: Atharva Korde.
Date and Time: Tuesday, 16 April. 5.10 pm  6.00 pm.
Refreshments will be served before the talk.
Venue: Ramanujan Hall, Department of Mathematics.
Title: Secret avatars of two spaces.
Abstract: The spaces SL(2, R) and SL(2,R)/SL(2, Z) look quite difficult to
visualize at first glance. In this talk, we shall see that these two
spaces are actually homeomorphic to some nicelooking spaces.
