.给出了有限维复半单李代数和紧半单李群的有限维表示的一个新的特征标公式。新公式的一些应用包括精确确定表示中的权重数,多重性的新递归公式,以及在某些情况下多重性本身的封闭公式。
. 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.
