© 2016 Elsevier Inc. We study the algebraic structure of repeated-root λ-constacyclic codes of prime power length p s over a finite commutative chain ring R with maximal ideal 〈γ〉. It is shown that, for any unit λ of the chain ring R, there always exists an element r∈R such that λ−r p s is not inv...
