Boundary integral scattering


I will give a transverse introduction to how Boundary
Integral techniques (or their numerical version, the Boundary
Element Method) have been and are being used for scattering
problems. While in the beginning the field of boundary integral
equations dealt mainly with simple exterior problems, the study of
the scattering of waves by penetrable obstacles offers a set of more
realistic problems where BEM techniques have often to be coupled
with better known methods for PDEs, such as the Finite Element
Method. We will see how a method-oriented approach can be valid for
wave problems in the frequency and time domains, and how the Laplace
transform plays a surprising role for numerical discretization in
the time domain.
