Centralisers in Classical Lie Algebras
Lewis William Topley
In this thesis we discuss some properties of centralisers in classical Lie algebas and related structures. Our results follow three distinct but related themes: the modular represe…

Derived subalgebras of centralisers and finite W-algebras
Alexander Premet, Lewis Topley
Let g = Lie(G) be the Lie algebra of a simple algebraic group G over an algebraically closed field of characteristic 0. Let e be a nilpotent element of g and let g_e = Lie(G_e) whe…
