A direct solver with O(N) complexity for integral equations on one-dimensional domains
Adrianna Gillman, Patrick Young, Per-Gunnar Martinsson
An algorithm for the direct inversion of the linear systems arising from Nystrom discretization of integral equations on one-dimensional domains is described. The method typically…

A fast solver for Poisson problems on infinite regular lattices
A. Gillman, P. G. Martinsson
The Fast Multipole Method (FMM) provides a highly efficient computational tool for solving constant coefficient partial differential equations (e.g. the Poisson equation) on infini…
