Let G be a reductive linear algebraic group over an algebraically closed field of characteristic p > 0. A subgroup of G is said to be separable in G if its global and infinitesimal centralizers have the same dimension. We study the interaction between the notion of separability and Serre's concept of G-complete reducibility for subgroups of G. The separability hypothesis appears in many general...

We prove the conjugacy separability of groups of the form G = (ax,...ar,bx,...,bs:aeli = bf> = (U(ax, ... , ar)V{bx , ... , bs))m = 1), where m > 1 .

Conjugacy separability of any group of the class of one-relator groups given by the presentation 〈a, b; [am, bn] = 1〉 (m, n > 1) is proven.
