RT info:eu-repo/semantics/article T1 On the structure of repeated-root polycyclic codes over local rings A1 Bajalan, Maryam A1 Martínez Moro, Edgar A1 Sobhani, Reza A1 Szabo, Steve A1 Yılmazgüç, Gülsüm Gözde K1 Matemáticas K1 Polycyclic code K1 Duality K1 Mattson-Solomon transform K1 Código policíclico K1 Dualidad K1 Transformación de Mattson-Solomon K1 12 Matemáticas AB This paper provides the Generalized Mattson Solomon polynomial for repeated-root polycyclic codes over local rings that gives an explicit decomposition of them in terms of idempotents. It also states some structural properties of repeated-root polycyclic codes over finite fields in terms of matrix product codes. Both approaches provide a description of the -dual code for a given polycyclic code.
