Let p be a prime such that pm ≡3 (mod 4). For any unit λ of Fpm , we determine the algebraic structures of λ-constacyclic codes of length 4ps over the finite commutative chain ring Fpm + uFpm , u2 = 0. If the unit λ ∈ Fpm is a square, each λ-constacyclic code of length 4ps is expressed as a direct sum of an -α-constacyclic code and an α- constacyclic code of length 2ps.
