Pseudodifferential Operators as Integral Operators,Symbols and admissible kernels are closely related based on the asymptotic expansions of the symbols and corresponding pseudohomogeneous expansions of the kernels as examined by Seeley . The main theorems in this context are Theorems 7.1.1, 7.1.6 and 7.1.7 below.

Boundary Integral Equations,sed on the direct approach. This reduction can be easily extended to more general partial differential equations. Here we will consider, in particular, the Helmholtz equation, the Lamé system, the Stokes equations and the biharmonic equation..For the Helmholtz equation, we also investigate the solut

Sobolev Spaces,e Sobolev spaces provide a very natural setting for variational problems. This chapter contains a brief summary of the basic definitions and results of the .–theory of Sobolev spaces which will suffice for our purposes. A more general discussion on these topics may be found in the standard books suc

Variational Formulations,differential equations. We collect some basic theorems in functional analysis which are needed for this purpose. In particular, Green‘s theorems and the Lax–Milgram theorem are fundamental tools for the solvability of boundary integral equations as well as for elliptic partial differential equations

Pseudodifferential Operators as Integral Operators,hich can be applied to problems in applications (Guiggiani , Schwab et al )..In this chapter, we discuss the interpretation of pseudodifferential operators as integral operators. In particular, we show that every classical pseudodifferential operator is an integral operator with integrable

Pseudodifferential and Boundary Integral Operators,he volume potentials, which are covered by Boutet de Monvel‘s work for even more general pseudodifferential operators satisfying the transmission conditions including those of operators with symbols of rational type..The last section is devoted to the concept of strong ellipticity and Fredholm prope
