Abstract

In this paper we compute the obstruction and the solutions of cyclic embedding problems given by

(E):0Z/nZEΓ=Z/nZ×m)×Z/nZ0,(E): \quad 0 \rightarrow \mathbb{Z}/n\mathbb{Z} \rightarrow E \rightarrow \Gamma=\mathbb{Z}/n\mathbb{Z} \times \stackrel{m)}{\cdots} \times \mathbb{Z}/n\mathbb{Z} \rightarrow 0 ,

with Z/nZ\mathbb{Z}/n\mathbb{Z} trivial Γ\Gamma-modulo, finding adequate representations of Γ\Gamma in the automorphisms group of a generalized Clifford algebra.
