A bound for the orders of centralizers of irreducible subgroups of algebraic groups
Abstract We prove that if 𝐺 is a connected semisimple algebraic group of rank 𝑟, and 𝐻 is a subgroup of 𝐺 that is contained in no proper parabolic subgroup, then we have | C G ( H ) | < c r | Z ( G ) | \lvert C_{G}(H)\rvert
