Ends 4
Looking at Nat |Id,Id| for the category of M-Sets when M is a monoid and contrasting this with Nat |U,U| where U: M-Set to Set is the forgetful functor. Ends 3
A couple more examples of ends. Firstly, otaining Nat |F,G| as an end. Secondly, a baby example of Tannakian reconstruction: if M is a monoid in Set, and U is the forgetful functor from M-Set to Set then Nat |U,U| = M. Ends 2
The first example of an end. Natural transformations of the identity as the end of the hom functor.
