Normalized Bicategories Internal to Groups and more General Mal'tsev Categories.

A detailed description of a normalized internal bicategory in the category of groups is derived from the general description of internal bicategories in weakly Mal'tsev categories endowed with a V-Mal'tsev operation in the sense of Pedicchio. The example of bicategory of paths in a topological abelian group is presented. [ABSTRACT FROM AUTHOR]
