Title: A bound for the orders of centralizers of irreducible subgroups of algebraic groups
Authors: Liebeck, M
Item Type: Journal Article
Abstract: We prove that if šŗ is a connected semisimple algebraic group of rank š‘Ÿ, and š» is a subgroup of šŗ that is contained in no proper parabolic subgroup, then we have |CG(H)|<cr|Z(G)| , where š‘ is an absolute constant ( c=16 if all simple factors of šŗ are classical, and cā‰¤197 in general).
