Description

This lecture discusses how to define an appropriate group action on the product of two G-objects when the forgotten functor preserves products, first in the abstract case and then in the concrete case where C=Ens. The instructor explains the consequences of this fact and how to define the action of G on the product. The lecture also covers the construction of automorphisms and the diagonal action in the context of group theory.
