Smoothed corners and scattered waves
Charles L. Epstein, Michael O'Neil
We introduce an arbitrary order, computationally efficient method to smooth corners on curves in the plane, as well as edges and vertices on surfaces in . The method i…

On the stability of time-domain integral equations for acoustic wave propagation
Charles L. Epstein, Leslie Greengard, Thomas Hagstrom
We give a principled approach for the selection of a boundary integral, retarded potential representation for the solution of scattering problems for the wave equation in an exteri…
