Algebraic Geometry and Topology Learning Seminar: Derived functors and sheaf cohomology

Wed, 11/04/2009 - 1:00pm, Skiles 255

Farbod Shokrieh, Ga Tech,         Organizer: John Etnyre

We will continue the study of derived functors between abelian categories. I will show why injective objects are needed for the construction. I will then show that, for any ringed space, the abelian category of all sheaves of Modules has enough injectives. The relation with Cech cohomology will also be studied.
