Fractional Diffusion on Graphs: Superposition of Laplacian Semigroups and Memory
Nikita Deniskin, Ernesto Estrada
Subdiffusion on graphs is often modeled by time-fractional diffusion equations, yet its structural and dynamical consequences remain unclear. We show that subdiffusive transport on…

Error analysis of Abate--Whitt methods for Inverse Laplace Transforms and a new algorithm for queuing theory applications
Nikita Deniskin, Federico Poloni
We study the accuracy of a class of methods to compute the Inverse Laplace Transform, the so-called \emph{Abate--Whitt methods} [Abate, Whitt 2006], which are based on a linear com…
