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 ...

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 ...
Corrección de borrado en ráfaga utilizando códigos LDPC construidos sobre matrices generadas por grupos combinados, polígonos anidados y matrices circulantes superpuestas
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-05-01)
En este artículo son propuestos procedimientos para la construcción de matrices base embazado en el álgebra moderna y en la geometría. Estas matrices sirven de plataforma para generar las matrices de verificación de paridad ...
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 ...
Landslide risk assessment considering socionatural factors: methodology and application to Cubatão municipality, São Paulo, Brazil
(2022-01-01)
The manuscript presents a methodology to integrate spatial information of susceptibility, vulnerability and rainfall thresholds to produce a dynamic landslide risk map. The inputs were combined in two matrices: combining ...
