© 2019 Elsevier B.V. Let p be an odd prime, s, m be positive integers, γ,λ be nonzero elements of the finite field F p m such that γ p s =λ. In this paper, we show that, for any positive integer η, the Hamming distances of all repeated-root λ-constacyclic codes of length ηp s can be determined by...
