Canonical Problems in Scattering and Potential Theory Part 1: Canonical Structures in Potential Theory (Monographs and Surveys in Pure and Applied Mathematics) by S.S. Vinogradov (Author), P. D. Smith (Author), E.D. Vinogradova (Author)Although the analysis of scattering for closed bodies of simple geometric shape is well developed, structures with edges, cavities, or inclusions have seemed, until now, intractable to analytical methods.
