Estimation of spectral gaps for sparse symmetric matrices
Michele Benzi, Michele Rinelli, Igor Simunec
In this paper we propose and analyze an algorithm for identifying spectral gaps of a real symmetric matrix by simultaneously approximating the traces of spectral projectors ass…

Computation of the von Neumann entropy of large matrices via trace estimators and rational Krylov methods
Michele Benzi, Michele Rinelli, Igor Simunec
We consider the problem of approximating the von Neumann entropy of a large, sparse, symmetric positive semidefinite matrix , defined as where $f(x)=-x…

Rational Krylov methods for fractional diffusion problems on graphs
Michele Benzi, Igor Simunec
In this paper we propose a method to compute the solution to the fractional diffusion equation on directed networks, which can be expressed in terms of the graph Laplacian as a…
