Profunctors are to functors what relations are to functions. I will define the bicategory of profunctors, show how Cat can embed into it, and how it is equivalent to the comma category Cat/2. We shall also see how every functor has a right adjoint as a profunctor.

This talk will be very elementary, and prior knowledge of Kan extensions is helpful but not entirely necessary.

This talk is part of the Junior Category Theory Seminar series.
