%0 Journal Article %T Centralisers in Classical Lie Algebras %A Lewis William Topley %J Mathematics %D 2013 %I arXiv %X 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 representation theory of centralisers, the sheets of simple Lie algebras and the representation theory of finite W-algebras and enveloping algebras. %U http://arxiv.org/abs/1310.2785v1
