Maximal subalgebras of Cartan type in the exceptional Lie algebras
Sebastian Herpel, David I. Stewart
In this paper we initiate the study of the maximal subalgebras of exceptional simple classical Lie algebras \g over algebraically closed fields k of positive characteristic p, such…

Stabilisation of the LHS spectral sequence for algebraic groups
Alison E. Parker, David I. Stewart
In this note, we consider the Lyndon--Hochschild--Serre spectral sequence corresponding to the first Frobenius kernel of an algebraic group G, computing the extensions between simp…

On the smoothness of normalisers and the subalgebra structure of modular Lie algebras
Sebastian Herpel, David I. Stewart
We provide results on the smoothness of normalisers in connected reductive algebraic groups over fields of positive characteristic . Specifically we we give bounds on $p…
