DESCRIPTION:Iulian Simion [EPFL]\nWe show how the characteristic independe
 nt description of the double centralizer Z of a unipotent element u is obt
 ained and how it can be used to determine these groups computationally. Fo
 r exceptional algebraic groups we obtain complete descriptions of the doub
 le centralizer of u in bad characteristic which can be used to address rel
 ated questions such as a characterizations of regular unipotent elements o
 r the decomposition of Z into Witt groups up to isogeny.
