In this paper, the properties of the generalized inverse of an arbitrary incidence matrix are examined in connection with the properties of the network flows in the corresponding directed graph and a ...

Matrix-variate Gaussian graphical models (GGM) have been widely used for modeling matrix-variate data. Since the support of sparse precision matrix represents the conditional independence graph among ...

Random matrix theory (RMT) has emerged as a powerful framework for analysing complex systems across physics, statistics and beyond, by examining the statistical properties of matrices with random ...
