Primitive idempotents of the hyperalgebra for the $r$ -th Frobenius kernel of $SL (2, k)$

Yutaka Yoshii

In this paper we construct primitive idempotents of the hyperalgebra for the $r$ -th Frobenius kernel of the algebraic group $SL (2, k)$ .

Some results on certain finite-dimensional subalgebras of the hyperalgebra of a universal Chevalley group

Yutaka Yoshii

In the hyperalgebra of the $r$ -th Frobenius kernel of a universal Chevalley group over a field of characteristic $p > 0$ , we study some subsets and the subalgebras generated by them…

Generating sets of the Jacobson radical of the hyperalgebra of (SL $_{2}$ ) $_{r}$

Yutaka Yoshii

We give generating sets of the Jacobson radical of the hyperalgebra of the $r$ -th Frobenius kernel of the algebraic group $SL_{2}$ over an algebraically closed field of charact…

Certain linear isomorphisms for hyperalgebras relative to a Chevalley group

Yutaka Yoshii

Let $G$ be a simply connected and simple algebraic group defined and split over a finite prime field $F_{p}$ of $p$ elements. In this paper, using an $F_{p}$ -linear m…
