随机矩阵特征值在“割的诞生”跃迁附近的双标度极限的Riemann-Hilbert方法

The Riemann-Hilbert approach to double scaling limit of random matrix eigenvalues near the "birth of a cut" transition

M. Y. Mo

摘要:

本文研究了随机酉矩阵系综在奇点附近的双标度极限,在奇点处,平衡测度的支撑产生一个新的割。利用Riemann-Hilbert方法得到了相关核的渐近性质。我们已经证明了临界点附近的核由带权$e^{-x^{2ν}}$的随机酉矩阵系综的相关核给出。这为Eynard以前的结果提供了严格的证明。

英文摘要:

In this paper we studied the double scaling limit of a random unitary matrix ensemble near a singular point where a new cut is emerging from the support of the equilibrium measure. We obtained the asymptotic of the correlation kernel by using the Riemann-Hilbert approach. We have shown that the kernel near the critical point is given by the correlation kernel of a random unitary matrix ensemble with weight $e^{-x^{2ν}}$. This provides a rigorous proof of the previous results of Eynard.
