A New Character Formula for Lie Algebras and Lie Groups
Journal of Lie Theory, Volume 22 (2012) no. 3, pp. 817-838
The aim of this paper is to present a new character formula for finite-dimensional representations of finite-dimensional complex semisimple Lie Algebras and compact semisimple Lie Groups. Some applications of the new formula include the exact determination of the number of weights in a representation, new recursion formulas for multiplicities and, in some cases, closed formulas for the multiplicities themselves.
