实Ginibre系综的特征值统计

Eigenvalue statistics of the real Ginibre ensemble

Peter J. Forrester, Taro Nagao

摘要:

真实的Ginibre系综由随机$N \times N$矩阵组成,这些矩阵由i.i.d.标准高斯输入利用斜正交多项式的方法,给出了实特征值和复特征值的广义$n$点相关,并给出了显式的$n \times n$ Pfcnans.给出了最大实特征值的累积概率密度的计算公式。这与May对生物网的稳定性分析有关。

英文摘要:

The real Ginibre ensemble consists of random $N \times N$ matrices formed from i.i.d. standard Gaussian entries. By using the method of skew orthogonal polynomials, the general $n$-point correlations for the real eigenvalues, and for the complex eigenvalues, are given as $n \times n$ Pfaffians with explicit entries. A computationally tractable formula for the cumulative probability density of the largest real eigenvalue is presented. This is relevant to May's stability analysis of biological webs.
