Skew Cyclic codes over $\F_q+u\F_q+v\F_q+uv\F_q$
Ting Yao, Minjia Shi, Patrick Solé · 2015-04-29 · via cs.IT updates on arXiv.org

In this paper, we study skew cyclic codes over the ring $R=\F_q+u\F_q+v\F_q+uv\F_q$, where $u^{2}=u,v^{2}=v,uv=vu$, $q=p^{m}$ and $p$ is an odd prime. We investigate the structural properties of skew cyclic codes over $R$ through a decomposition theorem. Furthermore, we give a formula for the number of skew cyclic codes of length $n$ over $R.$
