Über dieses Buch

This book presents a systematic exposition of the main ideas and methods in treating inverse problems for PDEs arising in basic mathematical models, though it makes no claim to being exhaustive. Mathematical models of most physical phenomena are governed by initial and boundary value problems for PDEs, and inverse problems governed by these equations arise naturally in nearly all branches of science and engineering.

The book’s content, especially in the Introduction and Part I, is self-contained and is intended to also be accessible for beginning graduate students, whose mathematical background includes only basic courses in advanced calculus, PDEs and functional analysis. Further, the book can be used as the backbone for a lecture course on inverse and ill-posed problems for partial differential equations.

In turn, the second part of the book consists of six nearly-independent chapters. The choice of these chapters was motivated by the fact that the inverse coefficient and source problems considered here are based on the basic and commonly used mathematical models governed by PDEs. These chapters describe not only these inverse problems, but also main inversion methods and techniques. Since the most distinctive features of any inverse problems related to PDEs are hidden in the properties of the corresponding solutions to direct problems, special attention is paid to the investigation of these properties.

Chapter 4. Inverse Problems for Hyperbolic Equations
Abstract
In the first part of this chapter we study two inverse source problems related to the second order hyperbolic equations \(u_{tt}-u_{xx}=\rho (x, t)g(t)\) and \(u_{tt}-u_{xx}=\rho (x, t)\varphi (x)\) for the quarter plane \(\mathbb {R}^2_+=\{(x, t)|\, x>0, t>0\}\), with Dirichlet type measured output data \(f(t):=u(x, t)\vert _{x=0}\).

Chapter 5. One-Dimensional Inverse Problems for Electrodynamic Equations
Abstract
Here \(H=(H_1,H_2,H_3)\) and \(E=( E_1,E_2,E_3)\) are vectors of electric and magnetic strengths, \(\varepsilon >0\), \(\mu >0\) and \(\sigma \) are the permittivity, permeability and conductivity coefficients, respectively, which define electro-dynamical parameters of a medium.
