Progress on the study of the Ginibre ensembles II: GinOE and GinSE

SS Byun, PJ Forrester - arXiv preprint arXiv:2301.05022, 2023 - arxiv.org
This is part II of a review relating to the three classes of random non-Hermitian Gaussian

Exact Persistence Exponent for the -Diffusion Equation and Related Kac Polynomials

M Poplavskyi, G Schehr - Physical review letters, 2018 - APS
We compute the persistence for the 2 D-diffusion equation with random initial condition, ie,
the probability p 0 (t) that the diffusion field, at a given point x in the plane, has not changed …

Large deviations and fluctuations of real eigenvalues of elliptic random matrices

SS Byun, L Molag, N Simm - arXiv preprint arXiv:2305.02753, 2023 - arxiv.org
We study real eigenvalues of $ N\times N $ real elliptic Ginibre matrices indexed by a non-

Harer-Zagier type recursion formula for the elliptic GinOE

SS Byun - Bulletin des Sciences Mathématiques, 2024 - Elsevier
We consider the real eigenvalues of the elliptic Ginibre matrix indexed by the non-Hermiticity
parameter τ∈[0, 1], and present a Harer-Zagier type recursion formula for the even moments …

Local central limit theorem for real eigenvalue fluctuations of elliptic GinOE matrices

PJ Forrester - Electronic Communications in Probability, 2024 - projecteuclid.org
Random matrices from the elliptic Ginibre orthogonal ensemble (GinOE) are a certain linear
combination of a real symmetric, and real anti-symmetric, Gaussian random matrix and …

Fluctuations and correlations for products of real asymmetric random matrices

W FitzGerald, N Simm - Annales de l'Institut Henri Poincare (B) …, 2023 - projecteuclid.org

matrices. These are matrices all of whose entries are real iid standard Gaussian random …

On the number of real eigenvalues of a product of truncated orthogonal random matrices

A Little, F Mezzadri, N Simm - Electronic Journal of Probability, 2022 - projecteuclid.org
Let O be chosen uniformly at random from the group of (N+ L)×(N+ L) orthogonal matrices.
Denote by O˜ the upper-left N× N corner of O, which we refer to as a truncation of O. In this …
