Solving a class of Robin problems in simply connected regions via integral equations with a generalized Neumann kernel


Shwan H.H. Al-Shatria, Ali H.M. Muridb,c,*, Munira Ismailb

 
ABSTRACT:     This paper presents a new boundary integral equation method for the solution of a class of Robin problems in bounded and unbounded simply connected regions. We show how to reformulate the Robin problems as Riemann-Hilbert problems which lead to systems of integral equations, related differential equations, and normalizing conditions that give rise to unique solutions. Numerical results on several test regions are presented to illustrate the solution technique for the Robin problems when the boundaries are sufficiently smooth.
