Sobolev Spaces, of boundary integral equations as described in the two previous chapters from the spaces of continuous or Holder continuous functions to appropriate Sobolev spaces. For the sake of brevity we will confine ourselves to interior boundary value problems in two dimensions.

Quadrature Methods,kernels. As we have pointed out in the previous chapter, the implementation of the degenerate kernel method, in general, requires some use of numerical quadrature. Therefore it is natural to try the application of numerical integration in a more direct approach to approximate integral operators by n
