Abstract:

In terms of the Chevalley bases, the representation matrices of generators of simple Lie algebras are able to be calculated principally. The difficulty occurs in some weights with high multiplicity.

Now, the problem is solved by the subduced representation of the simple Lie algebra with respect to A？ sub-algebra. Namely, the states with the multiple weight in the representation of a simple Lie algebra can be determined by its subduced representation with respect to A？.
