摘要：
Motivated by the work in [1] of Abualrub and Siap (2009), we investigate (1 + lambda u)-constacyclic codes over F-p[u]/< u(m)> of an arbitrary length, where lambda is an on zero element of F-p. We find the generator polynomials of (1 + lambda u)-constacyclic codes over F-p[u]/< u(m)>, and determine the number of (1 + lambda u)-constacyclic codes over F-p[u]/< u(m)> for a given length, as well as the number of code words in each such code. Some optimal linear codes over F-3 and F-5 are constructed from (1 + lambda u)-constacyclic codes over F-p + uF(p) under a Gray map. (C) 2010 The Franklin Institute. Published by Elsevier Ltd.
