Title: Computing Ext for complexes of sheaves on projective varieties

Abstract: I will describe an effective algorithm for computing Ext between bounded complexes of coherent sheaves on a projective variety. This is joint work with Souvik Dey, Guanyu Li, and Mahrud Sayrafi. I will start with an introduction to sheaves and sheaf cohomology directed at grad students.
