Levi decomposition of nilpotent centralisers in classical groups
Alex P. Babinski, David I. Stewart
Published 2016-11-03Version 1
We check that the connected centralisers of nilpotent elements in the orthogonal and symplectic groups have Levi decompositions in even characteristic. This provides a justification for the identification of the isomorphism classes of the reductive quotients as stated in [Liebeck, Seitz; Unipotent and Nilpotent Classes in Simple Algebraic Groups and Lie Algebras].
