On universal gradings, versal gradings and Schurian generated categories
Categories over a field k can be graded by different groups in a connected way; we consider morphisms between these gradings in order to define the fundamental grading group. We prove that this group is isomorphic to the fundamental group à la Grothendieck as considered in previous papers. In case t...
