On polycyclic codes over a finite chain ring
Galois images of polycyclic codes over a finite chain ring and their
annihilator dual are investigated. The case when a polycyclic codes is
Galois-disjoint over the ring is characterized and, the trace codes and
restrictions of free polycyclic codes over are also determined givind an
analogue of Delsarte theorem among trace map, any S -linear code and its
annihilator dual.Comment: Submitted to AMC. S.I. LAWC
