Plane functors
E. B. Katsov Moscow Chemical Technology Institute
Abstract:
Tensor products of functors over the set category are studied in this work. The concept of a plane functor is defined and a criterion under which a functor is planar is given, by means of which the existence of injective envelopes in the functor category over the set category is proved.
