厄米矩阵模型的体普适性及其相关性质

Bulk Universality and Related Properties of Hermitian Matrix Models

L. Pastur, M. Shcherbina

摘要:

在假定决定模型的势是全局$C^{2}$和局部$C^{3}$函数的条件下,给出了厄米矩阵模型谱块普适性的新证明(见定理\ref{t:U.t1}).与我们之前在\cite{Pa-Sh:97}中的证明一样,该证明基于正交多项式技术,但不使用正交多项式的渐近性。相反,我们得到的$sin$ -内核作为一个独特的解决方案,一定的非线性积分微分方程,从行列式公式的关联函数的模型。本文还对关于本征值的极限归一化计数测度的存在性和性质的论文\cite{BPS:95}进行了简化和加强。我们使用这些结果的普遍性的证明,我们相信,他们是独立的利益。

英文摘要:

We give a new proof of universality properties in the bulk of spectrum of the hermitian matrix models, assuming that the potential that determines the model is globally $C^{2}$ and locally $C^{3}$ function (see Theorem \ref{t:U.t1}). The proof as our previous proof in \cite{Pa-Sh:97} is based on the orthogonal polynomial techniques but does not use asymptotics of orthogonal polynomials. Rather, we obtain the $sin$-kernel as a unique solution of a certain non-linear integro-differential equation that follows from the determinant formulas for the correlation functions of the model. We also give a simplified and strengthened version of paper \cite{BPS:95} on the existence and properties of the limiting Normalized Counting Measure of eigenvalues. We use these results in the proof of universality and we believe that they are of independent interest.
