For a connected reductive algebraic group G, sheets are the maximal irreducible subsets of G consisting of conjugacy classes of the same dimension. In a joint work with F. Esposito we showed in 2012 how to parametrize sheets and we described classes lying in a given sheet, when the characteristic of the base field is good. These results can be used in order to show that the parts in a partition of G recently introduced by G. Lusztig are unions of sheets.
