Double skew cyclic codes over $\mathbb{F}_q+v\mathbb{F}_q$

In this study, in order to get better codes, we focus on double skew cyclic codes over the ring $\mathrm{R}= \mathbb{F}_q+v\mathbb{F}_q, ~v^2=v$ where $q$ is a prime power. We investigate the generator polynomials, minimal spanning sets, generator matrices, and the dual codes over the ring $\mathrm{R}$. As an implementation, the obtained results are illustrated with some good examples. Moreover, we introduce a construction for new generator matrices and thus achieve codes with better parameters than existing codes in the literature. Finally, we tabulate double skew cyclic codes of block length over the ring $\mathrm{R}$.
