Large deviations principle for the largest eigenvalue of Wigner matrices without Gaussian tails

We prove a large deviation principle for the largest eigenvalue of Wigner matrices without Gaussian tails, namely such that the distribution tails P(|X1,1| > t) and P(|X1,2| > t) behave like e−bt α and e−atα respectively for some a, b ∈ (0,+∞) and α ∈ (0, 2). The large deviation principle is of speed Nα/2 and with an explicit good rate function depending only on the tail distribution of the ent...

Moderate deviations for the eigenvalue counting function of Wigner matrices

We establish a moderate deviation principle (MDP) for the number of eigenvalues of a Wigner matrix in an interval. The proof relies on fine asymptotics of the variance of the eigenvalue counting function of GUEmatrices due to Gustavsson. The extension to certain families of Wigner matrices is based on the Tao and Vu Four Moment Theorem and applies localization results by Erdös, Yau and Yin. Mor...

Large Deviations without Principle

We develop a methodology for studying “large deviations type” questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are routed to the (weighted) shortest queue. It is not known whether the large deviations principle holds ...

The largest eigenvalue of rank one deformation of large Wigner matrices

The purpose of this paper is to establish universality of the fluctuations of the largest eigenvalue of some non necessarily Gaussian complex Deformed Wigner Ensembles. The real model is also considered. Our approach is close to the one used by A. Soshnikov (c.f. [12]) in the investigations of classical real or complex Wigner Ensembles. It is based on the computation of moments of traces of hig...

Large deviations of the maximum eigenvalue for wishart and Gaussian random matrices.

We present a Coulomb gas method to calculate analytically the probability of rare events where the maximum eigenvalue of a random matrix is much larger than its typical value. The large deviation function that characterizes this probability is computed explicitly for Wishart and Gaussian ensembles. The method is general and applies to other related problems, e.g., the joint large deviation func...
