Abstract
AbstractLet G be a simple algebraic group of adjoint type over an algebraically closed field k of bad characteristic. We show that its sheets of conjugacy classes are parametrized by G-conjugacy classes of pairs
$(M,{\mathcal O})$
where M is the identity component of the centralizer of a semisimple element in G and
${\mathcal O}$
is a rigid unipotent conjugacy class in M, in analogy with the good characteristic case.
