A Simple Method for Computing Singular or Nearly Singular Integrals on Closed Surfaces
Abstract We present a simple, accurate method for computing singular or nearly singular integrals on a smooth, closed surface, such as layer potentials for harmonic functions evaluated at points on or near the surface. The integral is computed with a regularized kernel and corrections are added for regularization and discretization, …
