Homomorphisms from $SL (2, k)$ to $SL (4, k)$ in positive characteristic

Ryuji Tanimoto

Let $k$ be an algebraically closed field of positive characteistic $p$ and let $SL (n, k)$ denote the special linear algebraic group of degree $n$ over $k$ . In this paper, we…

Triangular involutions of the four-dimensional polynomial ring in characteristic two

Ryuji Tanimoto

We are concerned with polynomial involutions in characteristic two. In this note, we look for involutions among triangular automorphisms of the four-dimensional polynomial ring in…

Representations of $G_{a} ⋊ G_{m}$ into $SL (3, k)$ in positive characteristic

Ryuji Tanimoto

Let $k$ be an algebraically closed field of positive characteristic $p$ . In this article, we classify representations of $G_{a} ⋊ G_{m}$ into $SL (3, k)$ ,…
