极值测度的极值分支数
The number of extremal components of an extremal measure
摘要：
已知Littlewood-Richardson系数可以使用某类测度来计算，并且当系数等于1时，这些测度具有刚性性质。刚性测度唯一分解为极值刚性测度的和。我们表明，极值和的数量密切相关的几何数据很容易获得的支持措施。
英文摘要：
It is known that the Littlewood-Richardson coefficients can be calculated using a certain class of measures, and these measures have a rigidity property when the coefficient is equal to 1. Rigid measures decompose uniquely into sums of extremal rigid measures. We show that the number of extremal summands is closely related with geometric data easily obtained from the support of the measure.
