Moments of the Hermitian Matrix Jacobi process [PDF]

open access: greenJournal of Theoretical Probability, 2017
In this paper, we compute the expectation of traces of powers of the Hermitian matrix Jacobi process for a large enough but fixed size. To proceed, we first derive the semi-group density of its eigenvalues process as a bilinear series of symmetric Jacobi

Painlevé kernels in Hermitian matrix models [PDF]

open access: greenConstructive Approximation, 2013
After reviewing the Hermitian one-matrix model, we will give a brief introduction to the Hermitian two-matrix model and present a summary of some recent results on the asymptotic behavior of the two-matrix model with a quartic potential.

Hermitian Matrix Diagonalization and Its Symmetry Properties [PDF]

open access: goldAdvances in High Energy Physics
A Hermitian matrix can be parametrized by a set consisting of its determinant and the eigenvalues of its submatrices. We established a group of equations which connect these variables with the mixing parameters of diagonalization.

Hermitian-Randić matrix and Hermitian-Randić energy of mixed graphs

open access: yesJournal of Inequalities and Applications, 2017
Let M be a mixed graph and H ( M ) $H(M)$ be its Hermitian-adjacency matrix. If we add a Randić weight to every edge and arc in M, then we can get a new weighted Hermitian-adjacency matrix. What are the properties of this new matrix?

Honeycombs from Hermitian Matrix Pairs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Knutson and Tao's work on the Horn conjectures used combinatorial invariants called hives and honeycombs to relate spectra of sums of Hermitian matrices to Littlewood-Richardson coefficients and problems in representation theory, but these relationships ...

Hermitian Matrix Model with Plaquette Interaction [PDF]

open access: yesNuclear Physics B, 1996
We study a hermitian $(n+1)$-matrix model with plaquette interaction, $\sum_{i=1}^n MA_iMA_i$. By means of a conformal transformation we rewrite the model as an $O(n)$ model on a random lattice with a non polynomial potential. This allows us to solve the

Hermitian vs. Anti-Hermitian 1-Matrix Models and Their Hierarchies [PDF]

open access: yesNuclear Physics B, 1991
Building on a recent work of \v C. Crnkovi\'c, M. Douglas and G. Moore, a study of multi-critical multi-cut one-matrix models and their associated $sl(2,C)$ integrable hierarchies, is further pursued.

A stronger version of matrix convexity as applied to functions of Hermitian matrices

open access: greenJournal of Inequalities and Applications, 1999
A stronger version of matrix convexity, called hyperconvexity is introduced. It is shown that the function is hyperconvex on the set of Hermitian matrices and is hyperconvex on the set of positive definite Hermitian matrices. The new concept makes it

Hermitian Hamiltonians: Matrix versus Schr${ö}$dinger's [PDF]

open access: green, 2016
We draw attention to the fact that a Hermitian matrix is always diagonalizable and has real discrete spectrum whereas the Hermitian Schr{ }dinger Hamiltonian: $H=p^2/2 +V(x)$, may not be so. For instance when $V(x)=x, x^3, -x^2$, $H$ does not have even one real discrete eigenvalue. Textbooks do not highlight this distinction. However, if $H$ has real

Dynamics of a rank-one perturbation of a Hermitian matrix [PDF]

open access: yesElectronic Communications in Probability, 2021
We study the eigenvalue trajectories of a time dependent matrix $ G_t = H+i t vv^*$ for $t \geq 0$, where $H$ is an $N \times N$ Hermitian random matrix and $v$ is a unit vector.
