Abstract: In this paper we classify group algebras over Galois rings containing self-dual ideals; i.e., ideals $C$ which satisfy $C=C^\perp$ with respect to the natural non-degenerate bilinear form given on group algebras.
Keywords: Ideals in group algebras, self-dual codes, self-dual modules, codes over Galois rings
