Abstract: Codes over finite commutative chain rings have been introduced as a generalization of codes over finite fields. Let S | R be a Galois extension of finite commutative chain rings. If C ⊆ S n is an S-code, it is possible to define, starting from C , two different R-codes:
Res(C ) = C ∩ R^n and Tr( C ), where Tr is the trace function. We will analyze the relationships between these R-codes and the
duality operator.
