Shulin Lyu, Yang Chen

摘要:

在由权重$x^α(1-x)^β,~x\in[0,1],~α,β>0$生成的Jacobi酉系综的硬边标度极限中,来自该系综的厄米矩阵的所有特征值位于区间$[t,1]$中的概率由Bessel核的Fredholm行列式给出。我们推导出这个贝塞尔核行列式的渐近常数。一个专业化的结果给出了常数的概率的渐近区间$(-a,a),a>0,$是免费的特征值的雅可比酉系综与对称重量$(1-x^2)^β, x\in[-1,1]$。

英文摘要:

In the hard edge scaling limit of the Jacobi unitary ensemble generated by the weight $x^α(1-x)^β,~x\in[0,1],~α,β>0$, the probability that all eigenvalues of Hermitian matrices from this ensemble lie in the interval $[t,1]$ is given by the Fredholm determinant of the Bessel kernel. We derive the constant in the asymptotics of this Bessel-kernel determinant. A specialization of the results gives the constant in the asymptotics of the probability that the interval $(-a,a),a>0,$ is free of eigenvalues in the Jacobi unitary ensemble with the symmetric weight $(1-x^2)^β, x\in[-1,1]$.
