给出了一个固定形状的随机Young表的下降数的期望,并显示了平均值周围的浓度。这个结果被推广到主要指标和其他下降函数。证明结合概率参数与组合特征理论。与Hecke代数的连接被提及。
The expectation of the descent number of a random Young tableau of a fixed shape is given, and concentration around the mean is shown. This result is generalized to the major index and to other descent functions. The proof combines probabilistic arguments together with combinatorial character theory. Connections with Hecke algebras are mentioned.
