Proceedings of the American Mathematical Society, Vol. 104, No. 2 (Oct., 1988), pp. 363-368 (6 pages) For a perfect field $F$ of arbitrary characteristic, the ...
We establish an irreducibility property for the characters of finite dimensional, irreducible representations of simple Lie algebras (or simple algebraic groups) over the complex numbers, i.e., that ...
Group gradings provide a powerful framework for decomposing algebraic structures into subspaces that are systematically indexed by a group. In the context of Lie algebras, which play a central role in ...
