Title: Six operations formalism for generalized operads.

Abstract: In this talk I will fill in an analogy between Verdier duality for sheaves and Koszul duality for algebras over operads.  To make this analogy precise we will consider the underlying categorical structure present in both situations.  Time permitting I will explain how understanding Koszul duality for modular operads from this perspective can be used to do computations in graph homology.
