This paper argues that the extent of financial contagion exhibits a form of phase transition:
as long as the magnitude of negative shocks affecting financial institutions are sufficiently …

The Handbook of Linear Algebra provides comprehensive coverage of linear algebra
concepts, applications, and computational software packages in an easy-to-use handbook …

Mutualistic interactions, those that are naturally beneficial for both interacting species, are
recurrently found in ecosystems. Observations of natural systems show that if we draw …

In this paper, we extend the notion of weak group inverse to rectangular matrices (called W-
weighted WG inverse) by using the weighted core EP inverse recently investigated. This …

The coordinate descent (CD) method is a classical optimization algorithm that has seen a
revival of interest because of its competitive performance in machine learning applications …

In this paper we extend the definition of BT inverse of square complex matrices to
rectangular matrices. This new generalized inverse (called the W-weighted BT inverse) …

Let m _ ij m^ ij be the hitting (mean first passage) time from state i to state j in an n-state
ergodic homogeneous Markov chain with transition matrix T. Let Γ Γ be the weighted …

Several new representations of the W-weighted Drazin inverse are introduced. These
representations are expressed in terms of various matrix powers as well as in terms of matrix …

In this paper, we present several representations of the W-weighted WG inverse. These
representations are expressed in terms of matrix powers as well as in terms of matrix …

Kernels and, broadly speaking, similarity measures on graphs are extensively used in graph-
based unsupervised and semi-supervised learning algorithms as well as in the link …
