摘要：

The notions of tensor product modulo q and exterior product modulo q of two G-crossed modules, where q is a positive integer and G is a group, are introduced and some properties are given. As an application we give the condition for the existence of a universal q-central relative extension of a surjective group homomorphism and describe this extension as an exterior product modulo q.
