Periodic Integral and Pseudodifferential Equations with Numerical Approximation

Classical boundary integral equations arising from the potential theory and acoustics (Laplace and Helmholtz equations) are derived. Using the parametrization of the boundary these equations take a form of periodic pseudodifferential equations. A general

Preface

This is a self-contained course book for graduate/postgradute students and it can be considered also as a scientific monograph. The purpose of the book is introduce the reader to the modern treatment of boundary value problems and integral equations. We do this by using the theory of pseudodifferential operators. The theory of pseudodifferential operators in ]Rn origins from the works of Kohn and Nirenberg, Hörmander '65, and others. In this monograph we cover the theory of periodie pseudodifferential equations, or pseudodifferential equations on the unit circle introduced by Agranovieh '79. During the last twenty years periodie pseudodifferential operators occurred to be also a powerful tool in numerieal analysis. The content of the book includes the following items. We begin with the Fredholm operators and Krylov subspace methods such as GMRES and conjugate gradien
