Query: Lie identities on symmetric elements of restricted enveloping algebras   Let L be a restricted Lie algebra over a field of characteristic p > 2 and
denote by u(L) its restricted enveloping algebra. We determine the conditions
under which the set of symmetric elements of u(L) with respect to the principal
involution is Lie solvable, Lie nilpotent, or bounded Lie Engel.
