Abstract
In this paper, we study the structural properties of (alpha+u(1)beta+u(2)gamma+u(1)u(2)delta)-constacyclic codes over R=F-q[u(1),u(2)]/< u(1)(2)-u(1),u(2)(2)-u(2),u(1)u(2)-u(2)u(1)> where q=p(m) for odd prime p and m >= 1. We derive the generators of constacyclic and dual constacyclic codes. We have shown that Gray image of a constacyclic code of length n is a quasi constacyclic code of length 4n. Also we have classified all possible self dual linear codes over this ring R. We have given the applications by computing non-binary quantum codes over this ring R.
