Some results on certain finite-dimensional subalgebras of the hyperalgebra of a universal Chevalley group
Published 12 Nov 2023 in math.RA | (2311.06806v1)
Abstract: 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 and give some results. We are particularly interested in the case that $p$ is 'very small' and the Dynkin diagram is not simply-laced.
