Spherical functions approach to sums of Random Hermitian Matrices
(Oxford University Press, 2017-07)
We present an approach to sums of random Hermitian matrices via the theory of spher- ical functions for the Gelfand pair (U(n) Herm(n), U(n)). It is inspired by a similar approach of Kieburg and Kösters for products of ...
Survival of Branching Random Walks in Random Environment

Potentials of random walks on trees
In this article we characterize inverse M-matrices and potentials whose inverses are supported on trees. In the symmetric case we show they are a Hadamard product of tree ultrametric matrices, generalizing a result by ...
BEAN PRODUCTIVITY UNDER DIFFERENT MATRIC POTENTIAL AND DEPLETION FACTORS OF WATER IN SOIL
(Univ Federal Mato Grosso, 2015-04-01)
Irrigated agriculture still suffers with decreases in productivity of crops on account of inefficient irrigation management therefore becomes paramount the use of methodologies and tools that allow the monitoring of water ...
THE CLASS OF INVERSE M-MATRICES ASSOCIATED TO RANDOM WALKS
(Society for Industrial and Applied Mathematics, 2013)
Given W = M−1, with M a tridiagonal M-matrix, we show that there are two diagonal matrices D,E and two nonsingular ultrametric matrices U, V such that DWE is the Hadamard product of U and V . If M is symmetric and row ...
Matrix Isolation of the Elusive Fluorocarbonylsulfenyl Fluoride Molecule FC(O)SF
(American Chemical Society, 2012-12-25)
The syn and anti conformers of the hitherto unknown fluorocarbonylsulphenyl fluoride FC(O)SF were formed through the photochemical reactions between OCS and F2, isolated in solid Ar. The reactions were followed by Fourier ...
Scaling Limits of Correlations of Characteristic Polynomials for the Gaussian beta-Ensemble with External Source
We study the averaged product of characteristic polynomials of large random matrices in the Gaussian beta-ensemble perturbed by an external source of finite rank. We prove that at the edge of the spectrum, the limiting ...
