A characterization of final functors between internal groupoids in exact categories
Theory Appl. Categ. 33, 265-275 (2018)
This paper provides three characterizations of final functors between internal groupoids in an exact category (in the sense of Barr). In particular, it is proved that a functor between internal groupoids is final if and only if it is internally full and essentially surjective.
