A New Maximal Subgroup of in Characteristic
David A. Craven, David I. Stewart, Adam R. Thomas
We prove the existence and uniqueness of a new maximal subgroup of the algebraic group of type in characteristic . This has type , and was missing from previous lists…
A note on extremely primitive affine groups
Timothy C. Burness, Adam R. Thomas
Let be a finite primitive permutation group on a set with nontrivial point stabilizer . We say that is extremely primitive if acts primitively on each of its…
The classification of extremely primitive groups
Timothy C. Burness, Adam R. Thomas
Let be a finite primitive permutation group on a set with nontrivial point stabilizer . We say that is extremely primitive if acts primitively on each of its…
Finite subgroups of simple algebraic groups with irreducible centralizers
Martin W. Liebeck, Adam R. Thomas
We determine all finite subgroups of simple algebraic groups that have irreducible centralizers - that is, centralizers whose connected component does not lie in a parabolic subgro…
