Large Deviations for Random Spectral Measures and Sum Rules [PDF]
, 2011 We prove a Large Deviation Principle for the random spec- tral measure associated to the pair $(H_N; e)$ where $H_N$ is sampled in the GUE(N) and e is a fixed unit vector (and more generally in the $\beta$- extension of this model).

Advanced Quantum Technologies, EarlyView.Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

On the Q‐Polynomial Property of Bipartite Graphs Admitting a Uniform Structure
Journal of Combinatorial Designs, Volume 34, Issue 2, Page 69-86, February 2026.ABSTRACT Let Γ denote a finite, connected graph with vertex set X. Fix x ∈ X and let ε ≥ 3 denote the eccentricity of x. For mutually distinct scalars { θ i * } i = 0 ε define a diagonal matrix A * = A * ( θ 0 * , θ 1 * , … , θ ε * ) ∈ Mat X ( R ) as follows: for y ∈ X we let ( A * ) y y = θ ∂ ( x , y ) *, where ∂ denotes the shortest path length ...

Non-Hermitian β-ensemble with real eigenvalues
AIP Advances, 2013 By removing the Hermitian condition of the so-called β-ensemble of tridiagonal matrices, an ensemble of non-Hermitian random matrices is constructed whose eigenvalues are all real.

Enumeration of simple random walks and tridiagonal matrices
, 2002 We present some old and new results in the enumeration of random walks in one dimension, mostly developed in works of enumerative combinatorics. The relation between the trace of the $n$-th power of a tridiagonal matrix and the enumeration of weighted ...

Checking nonsingularity of tridiagonal matrices
The Electronic Journal of Linear Algebra, 1999 In an earlier paper by \textit{I. Bar-On}, \textit{B. Codenotti} and \textit{M. Leoncini} [BIT 36, No. 2, 206-220 (1996; Zbl 0848.65029)] it was proved that checking robust nonsingularity of tridiagonal matrices can be performed in linear time. The present paper brings a detailed description of the algorithm.
