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 ...

Note on matrices of random numbers
(SAGE Publications, 2000-04)
The statistical and structural characteristics of 13 matrices of random numbers in which both the cells and the entries were randomly chosen are discussed. Each matrix was explored considering row means, standard deviations, ...
Potentials of random walks on trees
(Elsevier, 2016)
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 ...
