A simple construction of basic polynomials invariant under the Weyl group of the simple finite-dimensional complex Lie algebra
For every simple finite-dimensional complex Lie algebra, I give a simple construction of all (except for the Pfaffian) basic polynomials invariant under the Weyl group. The answer is given in terms of the two basic polynomials of smallest degree.
