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…

Fast Iterative Solution of the Optimal Transport Problem on Graphs
Enrico Facca, Michele Benzi
In this paper, we address the numerical solution of the Optimal Transport Problem on undirected weighted graphs, taking the shortest path distance as transport cost. The optimal so…
