Skew cyclic codes over $\mathbb{F}_{q}+v\mathbb{F}_{q}+v^{2}\mathbb{F}_{q}$

Abstract: In this article, we study skew cyclic codes over ring $$R=\mathbb{F}<em>{q}+v\mathbb{F}</em>{q}+v<sup>{2}\mathbb{F}_{q}$$, where $q=p<sup>{m}$, $p$ is an odd prime and $v<sup>{3}=v$. We describe generator polynomials of skew cyclic codes over this ring and investigate the structural properties of skew cyclic codes over $R$ by a decomposition theorem. We also describe the generator polynomials of the duals of skew cyclic codes. Moreover, the idempotent generators of skew cyclic codes over $\mathbb{F}_{q}$ and $R$ are considered.
