Fixed point spaces in actions of exceptional algebraic groups

Ross Lawther, Martin W. Liebeck and Gary M. Seitz

Vol. 205 (2002), No. 2, 339–391
Abstract

Let G be a simple algebraic group of exceptional type acting transitively on an algebraic variety. We provide estimates for the dimensions of the subvarieties of fixed points of elements of G. These translate into estimates for the dimensions of intersections of conjugacy classes of G with closed subgroups.
