Abstract
Assume that a basic algebra over an algebraically closed field with a basic set of primitive idempotents has the property that for all . Let be a nonzero integer, and and two automorphisms of the repetitive category of with jump (namely, they send to , where is the -th copy of in for all ). If and coincide on the objects and if there exists a map such that for all morphisms , then the orbit categories and are isomorphic as -graded categories.
