Internal categorical structures in weakly Mal'tsev categories
 
 
Description:  It is well known that in the context of a Mal'tsev category the three notions: multiplicative graph, internal category, internal groupoid; coincide and are completely determined by the respective underlying reflexive graph. In this talk we will see that in the more general case of a weakly Mal'tsev category this is no longer true in general.
Nevertheless there is still an intrinsic neat characterization for these structures. We will also give some examples and analyze under which conditions the previous coincidence of structures still holds.
