Speaker:  Vladimir Hinich (University of Haifa)

Topic: So, what is a derived functor?

Place:    room 614 in the Science & Education Building

Time   12:10

In the context of infinity categories, we rethink the notion of derived functor in terms of

correspondences. Derived functors in our sense, when exist,

are given by a Kan extension, but their existence is a

strictly stronger property than that of existence of Kan extensions.

Our definition is especially convenient for the description

of a passage from an adjoint pair of functors to the respective

derived adjoint pair. Canonicity of this passage becomes obvious.
