Description
Summary:© 2020, Springer-Verlag GmbH, DE. Let p be an odd prime, and δ be an arbitrary unit of the finite chain ring Fpm+uFpm(u2=0). The Hamming distances of all δ-constacyclic codes of length 2 ps over Fpm+uFpm are completely determined. We provide some examples from which some codes have better parameters than the existing ones. As applications, we determine all MDS repeated-root δ-constacyclic codes of length 2 ps over Fpm+uFpm.
