Relative complete reducibility and normalised subgroups

Maike Gruchot, Alastair Litterick, Gerhard Roehrle

We study a relative variant of Serre's notion of $G$ -complete reducibility for a reductive algebraic group $G$ . We let $K$ be a reductive subgroup of $G$ , and consider subgroups of…

Further Rigid Triples of Classes in $G_{2}$

Matthew Conder, Alastair Litterick

We establish the existence of two rigid triples of conjugacy classes in the algebraic group $G_{2}$ in characteristic $5$ , complementing results of the second author with Liebeck a…

Reducible subgroups of exceptional algebraic groups

Alastair J. Litterick, Adam R. Thomas

Let $G$ be a simple algebraic group over an algebraically closed field. A closed subgroup $H$ of $G$ is called $G$ -completely reducible ( $G$ -cr) if, whenever $H$ is contained in a…
