Abstract
In this paper, we study \(\lambda \)-constacyclic codes of length \(p^s\) over the ring \(R=F_{p^m}[u,v]/\langle u^2, v^2, uv-vu \rangle \), where \(\lambda = (\lambda _1+u\lambda _2)\) and \((\lambda _1+v\lambda _3)\) such that \(\lambda _i~;~ i=1,2,3\) are non zero elements of \(F_{p^m}\) for prime number p. Complete ideal structure of the rings \(R[x]/ \langle x^{p^s} - \lambda \rangle \) has been presented. We have also discussed the dual \(\lambda \)-constacyclic codes over R. At last, we extend our results to \(\lambda \)-constacyclic codes of length \(2p^s\) over R.
