Spectral and computational aspects of a regularized fractional Laplacian for non-local diffusion on graphs
Alessandro Filippo, Mariarosa Mazza
The fractional Laplacian has been widely used to model non-local diffusion on graphs, allowing interactions that extend beyond immediate neighbors. However, it suffers from a struc…

Stage-Parallel Implicit Runge--Kutta methods via low-rank matrix equation corrections
Fabio Durastante, Mariarosa Mazza
Implicit Runge--Kutta (IRK) methods are highly effective for solving stiff ordinary differential equations (ODEs) but can be computationally expensive for large-scale problems due…
