Regular versus homological closure operators
 
 
Description:  In this talk we will compare results obtained by the speaker on weak heredity of regular closure operators on topological and abelian categories (cf. [2]), with recent results by Bourn-Gran [1] on weak heredity of homological closure operators on protomodular categories.
