Abstract
For an -th power of a unit in a finite chain ring we prove that -constacyclic repeated-root codes over some finite chain rings are equivalent to cyclic codes. This allows us to simplify the structure of some constacylic codes. We also study the -constacyclic codes of length over the Galois ring .
