Canadian journal of mathematics, Tome 54 (2002) no. 5, pp. 970-997

In this article we state and prove precise theorems on the homotopy classification of graded categorical groups and their homomorphisms. The results use equivariant group cohomology, and they are applied to show a treatment of the general equivariant group extension problem.
