Representation Formulae, Local Coordinates and Direct Boundary Integral Equations,achinery. This includes the basic definitions and properties of classical function spaces and distributions, the Fourier transform and the definition of Hadamard‘s finite part integrals which, in fact, represent the natural regularization of homogeneous distributions and of the hypersingular boundary integral operators.

Low Threshold Organic Semiconductor LasersThis chapter serves as a basic introduction to the reduction of elliptic boundary value problems to boundary integral equations. We begin with model problems for the Laplace equation. Our approach is the direct formulation based on Green‘s formula, in contrast to the indirect approach based on a layer ansatz.

https://doi.org/10.1007/978-3-319-01267-4The pseudodifferential operators provide a unified treatment of differential and integral operators. They are based on the intensive use of the Fourier transformation . (3.1.12) and its inverse . . .(3.1.14). The linear pseudodifferential operators can be characterized by generalized Fourier multipliers, called symbols.

Low Threshold Organic Semiconductor LasersAll of the integral operators with nonintegrable kernels are given in terms of computable Hadamard‘s partie finie, i.e. finite part integrals , which can be applied to problems in applications (Guiggiani , Schwab et al ).
