Asymptotics of Hankel determinants with a Laguerre-type or Jacobi-type potential and Fisher-Hartwig singularities

Christophe Charlier, Roozbeh Gharakhloo

摘要:

我们得到了权具有一截正则势和Fisher-Hartwig奇异性的$n \times n$ Hankel行列式的大$n$渐近性.我们限制我们的注意力的情况下,相关的平衡措施拥有一个软边和一个硬边(Laguerre型)或两个硬边(Jacobi型)。本文还介绍了随机矩阵理论中的一些应用。特别是,我们可以推断出我们的结果渐近的配分函数与奇点,中心极限定理,相关的特征多项式,间隙概率(分段常数)稀疏拉盖尔和雅可比型合奏。最后,我们提到了刚性和高斯乘性混沌的主题的一些联系。

英文摘要:

We obtain large $n$ asymptotics of $n \times n$ Hankel determinants whose weight has a one-cut regular potential and Fisher-Hartwig singularities. We restrict our attention to the case where the associated equilibrium measure possesses either one soft edge and one hard edge (Laguerre-type) or two hard edges (Jacobi-type). We also present some applications in the theory of random matrices. In particular, we can deduce from our results asymptotics for partition functions with singularities, central limit theorems, correlations of the characteristic polynomials, and gap probabilities for (piecewise constant) thinned Laguerre and Jacobi-type ensembles. Finally, we mention some links with the topics of rigidity and Gaussian multiplicative chaos.
