Isakov, Victor Inverse source problems. (English) Zbl 0721.31002 Mathematical Surveys and Monographs, 34. Providence, RI: American Mathematical Society (AMS). xiv, 193 p. (1990). The book is a review of the results on the inverse problem of potential theory (Chapters 2-5) supplemented by a discussion of some inverse problems for parabolic and hyperbolic equations (Chapters 6, 7). In Chapter 1 some auxiliary material is given. In Chapter 2 the results are described. In Chapter 3 uniqueness theorems are given. They are based on the idea of P. Novikov (1938). In Chapter 4 singularities of the exterior potentials are studied: relations between smoothness of the continuation of the potential across \(\Gamma\) and smoothness of \(\Gamma\), provided that the source and the coefficients of the operator are smooth. Some results of V. K. Ivanov are given. Chapter 5 deals with the existence of the mass distribution which generates a given harmonic function as an exterior potential. This is largely an open problem. Local existence results are described. An example of nonexistence is given. Chapters 6 and 7 deal with some inverse problems of parabolic and hyperbolic equations. Typically the extra data are given on the lateral surface of the cylinder or on its upper base.
