Vector invariants for two-dimensional orthogonal groups over finite fields

Yin Chen

Let $F_{q}$ be a finite field of characteristic $2$ and $O_{2}^{+} (F_{q})$ be the $2$ -dimensional orthogonal group of plus type over $F_{q}$ . Consider the st…

Geometry of Yang-Baxter matrix equations over finite fields

Yin Chen, Shaoping Zhu

Let $A$ be a $2 \times 2$ matrix over a finite field and consider the Yang-Baxter matrix equation $X A X = A X A$ with respect to $A$ . We use a method of computational ideal theory to exp…
