%0 Journal Article %T Counting semisimple orbits of finite Lie algebras by genus %A Jason Fulman %J Mathematics %D 1997 %I arXiv %X The adjoint action of a finite group of Lie type on its Lie algebra is studied. A simple formula is conjectured for the number of split semisimple orbits of a given genus. This conjecture is proved for type A, and partial results are obtained for other types. For type A a probabilistic interpretation is given in terms of card shuffling. %U http://arxiv.org/abs/math/9712246v2
