In many fields of application of mathematics, progress is crucially
dependent on the good flow of information between (i) theoretical
mathematicians looking for applications, (ii) mathematicians working in
applications in need of theory, and (iii) scientists and engineers
applying mathematical models and methods. The intention of this book is
to stimulate this flow of information. In the first three chapters
(accessible to third year students of mathematics and physics and to
mathematically interested engineers) applications of Abel integral
equations are surveyed broadly including determination of potentials,
stereology, seismic travel times, spectroscopy, optical fibres. In
subsequent chapters (requiring some background in functional analysis)
mapping properties of Abel integral operators and their relation to
other integral transforms in various function spaces are investi- gated,
questions of existence and uniqueness of solutions of linear and
nonlinear Abel integral equations are treated, and for equations of the
first kind problems of ill-posedness are discussed. Finally, some
numerical methods are described. In the theoretical parts, emphasis is
put on the aspects relevant to applications.
