Exponential convergence for multipole and local expansions and their translations for sources in layered media: 2-D acoustic wave
Wenzhong Zhang, Bo Wang, Wei Cai
In this paper, we will first give a derivation of the multipole expansion (ME) and local expansion (LE) for the far field from sources in general 2-D layered media and the multipol…

A hierarchical random compression method for kernel matrices
Duan Chen, Wei Cai
In this paper, we propose a hierarchical random compression method (HRCM) for kernel matrices in fast kernel summations. The HRCM combines the hierarchical framework of the H-matri…

What Is the Fractional Laplacian?
Anna Lischke, Guofei Pang, Mamikon Gulian +8
The fractional Laplacian in R^d has multiple equivalent characterizations. Moreover, in bounded domains, boundary conditions must be incorporated in these characterizations in math…
