Title: The Grothendieck spectral sequence

Abstract:

Suppose F : A → B and G : B → C are left exact functors between abelian categories, where A and B have enough injectives. For each object of A, given some extra conditions on F and G, there exists a convergent spectral sequence called the Grothendieck spectral sequence (GSS), which tells us how to compose the right derived functors of F and G, in order to get the right derived functors of GF. I prove the theorem by Grothendieck that encapsulates this property. I also briefly provide a context in which a GSS is constructed.
