Let $k$ be the algebraic closure of a finite field and let $A$ be a finite dimensional $k$-algebra with a
Frobenius morphism $F:A\to A$. In the present paper we establish a
relation between the stable module category of the repetitive
algebra of $A$ and that of the repetitive algebra of the
fixed-point algebra $A^F$. As an application, we provide an alternative proof of
[4. Theorem 5.4].
