The Wigner-Dyson-Gaudin-Mehta Conjecture

A comment on the Wigner - Dyson - Mehta bulk universality conjecture for Wigner matrices ∗

Recently we proved [3, 4, 6, 7, 9, 10, 11] that the eigenvalue correlation functions of a general class of random matrices converge, weakly with respect to the energy, to the corresponding ones of Gaussian matrices. Tao and Vu [15] gave a proof that for the special case of Hermitian Wigner matrices the convergence can be strengthened to vague convergence at any fixed energy in the bulk. In this...

Difference Macdonald - Mehta conjecture

with respect to the Gaussian measure. Macdonald extended it from An−1 to other root systems and verified his conjecture for classical ones by means of the Selberg integrals [M1]. It was established by Opdam in [O1] in full generality using the shift operators. The integral is an important normalization constant for a k-deformation of the Hankel transform introduced by Dunkl [D]. The generalized...

Disturbing the q-Dyson Conjecture

I discuss the computational methods behind the formulation of some conjectures related to variants on Andrews’ q-Dyson conjecture.

Wigner–Dyson statistics from the replica method

We compute the correlation functions of the eigenvalues in the Gaussian unitary ensemble using the fermionic replica method. We show that non-trivial saddle points, which break replica symmetry, must be included in the calculation in order to correctly reproduce the exact asymptotic behaviour of the correlation functions at a large distance.
