© 2016 Elsevier B.V. For any odd prime p such that p m ≡1(mod4), the structures of all λ-constacyclic codes of length 4p s over the finite commutative chain ring F p m +uF p m (u 2 =0) are established in terms of their generator polynomials. If the unit λ is a square, each λ-constacyclic code of len...
