Painlevé V for a Jacobi unitary ensemble with random singularities

Mengkun Zhu, Chuanzhong Li, Yang Chen

In this paper, we focus on the relationship between the fifth Painlevé equation and a Jacobi weight perturbed with random singularities, \begin{equation*} w(z)=\left(1-z^2\right)^α…

Smallest Eigenvalue of Large Hankel Matrices at Critical Point: Comparing Conjecture With Parallelised Computation

Yang Chen, Jakub Sikorowski, Mengkun Zhu

We propose a novel parallel numerical algorithm for calculating the smallest eigenvalues of highly ill-conditioned matrices. It is based on the {\it LDLT} decomposition and involve…
