David Stewart (Newcastle, Maths): Maximal subalgebras of modular Lie algebras

Time and Location:

16:00 in CM107 (Durham)

Abstract:

The question of classifying maximal subalgebras of Lie algebras goes all the way back to papers of Sophus Lie himself in the 1890s and has a long history from Dynkin onwards. We report on the latest developments in classifying the maximal subalgebras of Lie algebras of simple algebraic groups over algebraically closed fields of positive characteristic, a reasonable task thanks to the Premet-Strade classification of simple Lie modular algebras in characteristics at least 5. This is joint work with Sasha Premet.
