Abstract:
The Dirichlet problem u sub xx u sub yy 0, x,y epsilon R u g, x,y epsilon C 1 is considered. Here R is a bounded domain in the x,y-plane with boundary C. C is of bounded rotation and g is bounded and Borel-measurable. It is shown that if C has no cusps then the solution of 1 can be obtained in terms of the double-layer potential phi which satisfies the Lebesgue-Stieltjes integral equation IT phi gpi. Here T phis the integral over C of phisigma Pi sub s dsigma, where s denotes arc-length on C, and pi sub s is a Lebesgue-Stieltjes measure which depends on C. The case when C has cusps is also considered. The report also contains a lengthy survey of th literature on double-layer potentials. Author
