Stability of the Nyström Method for the Sherman–Lauricella Equation

Didenko, Victor and Helsing, Johan LU (2011) In SIAM Journal on Numerical Analysis 49(3). p.1127-1148
Abstract
The stability of the Nyström method for the Sherman–Lauricella equation on piecewise smooth closed simple contour $\Gamma$ is studied. It is shown that in the space $L_2$ the method is stable if and only if certain operators associated with the corner points of $\Gamma$ are invertible. If $\Gamma$ does not have corner points, the method is always stable. Numerical experiments show the transformation of solutions when the unit circle is continuously transformed into the unit square, and then into various rhombuses. Examples also show an excellent convergence of the method.
