Damian Sercombe: Unipotent normal subgroups of algebraic groups
Let G be an affine algebraic group over a field k. We show there exists a unipotent normal subgroup of G which contains all other such subgroups; we call it the restricted unipotent radical Rad_u(G) of G. We investigate some properties of Rad_u(G), and study those G for which Rad_u(G) is trivial. In particular, we relate these notions to their well-known analogues for smooth connected affine k-groups.
