广义Ewens测度下的随机置换矩阵

Random permutation matrices under the generalized Ewens measure

Christopher Hughes, Joseph Najnudel, Ashkan Nikeghbali, Dirk Zeindler

摘要:

我们考虑了对称群的Ewens测度的推广,计算了特征多项式的矩和类似的乘法统计量。此外,我们还研究了线性统计量(如置换矩阵或圈积的迹)在这种新测度下的渐近性态。

英文摘要:

We consider a generalization of the Ewens measure for the symmetric group, calculating moments of the characteristic polynomial and similar multiplicative statistics. In addition, we study the asymptotic behavior of linear statistics (such as the trace of a permutation matrix or of a wreath product) under this new measure.
