A high-order singularity subtraction technique for the Laplace equation in the plane

We present a simple high-order singularity subtraction technique for the numerical evaluation of Laplace boundary integral operators and layer potentials in two-spatial dimensions. The proposed technique allows integral operators and layer potentials to be expressed in terms of integrands of prescribed smoothness. The resulting boundary integrals can then be easily, […]
