Abstract: Let be an matrix ring with entries in the field *F*, and let be the standard polynomial in *k* variables. Amitsur-Levitzki have shown that vanishes for all specializations of to elements of . Now, with respect to the transpose, let be the set of antisymmetric elements and let be the set of symmetric elements. Kostant has shown using Lie group theory that for *n* even vanishes for all specializations of to elements of . By strictly elementary methods we have obtained the following strengthening of Kostant's theorem:

vanishes for all specializations of to elements of , *for all n*.

vanishes for all specializations of to elements of and of to an element of , for all *n*.

vanishes for all specializations of to elements of and of to an element of , for *n* odd.

These are the best possible results if *F* has characteristic 0; a complete analysis of the problem is also given if *F* has characteristic 2.
