✦ Synopsis

A singular perturbed convection-di usion problem on polygons is considered. Several boundary integral equations are used for the numerical approximation of the problem. An estimate for the single-layer integral operator in dependence of the perturbation parameter is obtained. The convergence of Galerkin and of Galerkin-Petrov schemes are discussed. Numerical results are presented.

In this paper a boundary problem is considered for which the boundary is to be determined as part of the solution. A time-dependent problem involving linear di usion in two spatial dimensions which results in a moving free boundary is posed. The fundamental solution is introduced and Green's Theorem
