Separable deformations of the generalized quaternion group algebras

The group algebras kQ(2n) of the generalized quaternion groups Q(2n) over fields k which contain F2n-2 are deformed to separable k((t))-algebras [kQ(2n)](t). The dimensions of the simple components of <(k((t)))over bar> circle times(k((t))) [kQ(2n)](t) over the algebraic closure <(k((t)))over bar>, and those of CQ(2n) over C are the same, yielding strong solutions of the Donald-Flanigan conjecture for the generalized quaternion groups.
