Can the a.c.s. notion and the GLT theory handle approximated PDEs/FDEs with either moving or unbounded domains?

Andrea Adriani, Alec Jacopo Almo Schiavoni-Piazza, Stefano Serra-Capizzano +1

In the current note we consider matrix-sequences ${B_{n, t}}_{n}$ of increasing sizes depending on $n$ and equipped with a parameter $t > 0$ . For every fixed $t > 0$ , we assume that eac…

Asymptotic spectral properties and preconditioning of an approximated nonlocal Helmholtz equation with Caputo fractional Laplacian and variable coefficient wave number $μ$

Andrea Adriani, Rosita Luisa Sormani, Cristina Tablino-Possio +2

The current study investigates the asymptotic spectral properties of a finite difference approximation of nonlocal Helmholtz equations with a Caputo fractional Laplacian and a vari…
