Moment Theory and Some Inverse Problems in Potential Theory and Heat Conduction

2002 VIII, 183 p. Softcover
3-540-44006-2

Moment Theory is not a new subject; however, in classical treatments, the ill-posedness of the problem is not taken into account - hence this monograph. Assuming a "true" solution to be uniquely determined by a sequence of moments (given as integrals) of which only finitely many are inaccurately given, the authors describe and analyze several regularization methods and derive stability estimates. Mathematically, the task often consists in the reconstruction of an analytic or harmonic function, as is natural from concrete applications discussed (e.g. inverse heat conduction problems, Cauchy's problem for the Laplace equation, gravimetry). The book can be used in a graduate or upper undergraduate course in Inverse Problems, or as supplementary reading for a course on Applied Partial Differential Equations.

Keywords: Moment problems, inverse problems, potential theory, reconstruction of analytic functions, regularization methods

Contents: Introduction.- Mathematical Preliminaries.- Regularization of moment problems by trancated expansion and by the Tikhonov method.- Backus-Gilbert regularization of a moment problem.- The Hausdorff moment problem: regularization and error estimates.- Analytic functions: reconstruction and Sinc approximations.- Regularization of some inverse problems in potential theory.- Regularization of some inverse problems in heat conduction.- Epilogue.- References.- Index.

This book is an introductory graduate-level textbook on the theory of smooth manifolds. Its goal is to familiarize students with the tools they will need in order to use manifolds in mathematical or scientific research - smooth structures, tangent vectors and covectors, vector bundles, immersed and embedded submanifolds, tensors, differential forms, de Rham cohomology, vector fields, flows, foliations, Lie derivatives, Lie groups, Lie algebras, and more. The approach is as concrete as possible, with pictures and intuitive discussions of how one should think geometrically about the abstract concepts, while making full use of the powerful tools that modern mathematics has to offer. Along the way, the book introduces students to some of the most important examples of geometric structures that manifolds can carry, such as Riemannian metrics, symplectic structures, and foliations. The book is aimed at students who already have a solid acquaintance with general topology, the fundamental group, and covering spaces, as well as basic undergraduate linear algebra and real analysis.

John M. Lee is Professor of Mathematics at the University of Washington in Seattle, where he regularly teaches graduate courses on the topology and geometry of manifolds. He was the recipient of the American Mathematical Societys Centennial Research Fellowship and he is the author of two previous Springer books, Introduction to Topological Manifolds (2000) and Riemannian Manifolds: An Introduction to Curvature (1997).

Contents: Preface.- Smooth Manifolds.- Smooth Maps.- Tangent Vectors.- Vector Fields.- Vector Bundles.- The Cotangent Bundle.- Submersions, Immersions, and Embeddings.- Submanifolds.- Embedding and Approximation Theorems.- Lie Group Actions.- Tensors.- Differential Forms.- Orientations.- Integration on Manifolds.- De Rham Cohomology.- The De Rham Theorem.- Integral Curves and Flows.- Lie Derivatives.- Integral Manifolds and Foliations.- Lie Groups and Their Lie Algebras.- Appendix: Review of Prerequisites.- References.- Index.

Suranyi, Janos, Eotvos University, Budapest, Hungary; Erdos, Paul ; Guiduli, B., Morgan Stanley, New York, NY, USA

Topics in the Theory of Numbers

Approx. 290 pp. 32 figs. Hardcover
0-387-95320-5

This rather unique book is a guided tour through number theory. While most introductions to number theory provide a systematic and exhaustive treatment of the subject, the authors have chosen instead to illustrate the many varied subjects by associating recent discoveries, interesting methods, and unsolved problems. In particular, we read about combinatorial problems in number theory, a branch of mathematics co-founded and popularized by Paul Erdos. Janos Suranyis vast teaching experience successfully complements Paul Erdos'ability to initiate new directions of research by suggesting new problems and approaches. This book will surely arouse the interest of the student and the teacher alike.
Until his death in 1996, Professor Paul Erdos was one of the most prolific mathematicians ever, publishing close to 1,500 papers. While his papers contributed to almost every area of mathematics, his main research interest was in the area of combinatorics, graph theory, and number theory. He is most famous for proposing problems to the mathematical community which were exquisitely simple to understand yet difficult to solve. He was awarded numerous prestigious prizes including the Frank Nelson Cole prize of the AMS.
Professor Janos Suranyi is a leading personality in Hungary, not just within the mathematical community, but also in the planning and conducting of different educational projects which have led to a new secondary school curriculum. His activity has been recognized by, amongst others, the Middle Cross of the Hungarian Decoration and the Erdos Award of the World Federation of National Mathematical Competitions.

DIFFERENTIAL GEOMETRY AND RELATED TOPICS
Proceedings of the International Conference on Modern Mathematics and the International Symposium on Differential Geometry, Fudan University, China 19 - 23 September 2001

The International Conference on Modern Mathematics and the International Symposium on Differential Geometry, in honor of Professor Su Buchin on the centenary of his birth, were held in September 2001 at Fudan University, Shanghai, China. Around 100 mathematicians from China, France, Japan, Singapore and the United States participated.
The proceedings cover a broad spectrum of advanced topics in mathematics, especially in differential geometry, such as some problems of common interest in harmonic maps, submanifolds, the Yang?Mills field and the geometric theory of solitons.

Readership: Researchers and graduate students in mathematics.

SOLITON EQUATIONS AND HAMILTONIAN SYSTEMS
2nd Edition

Advanced Series in Mathematical Physics - Vol. 26

The theory of soliton equations and integrable systems has developed rapidly during the last 30 years with numerous applications in mechanics and physics. For a long time, books in this field have not been written but the flood of papers was overwhelming: many hundreds, maybe thousands of them. All this output followed one single work by Gardner, Green, Kruskal, and Mizura on the Korteweg-de Vries equation (KdV), which had seemed to be merely an unassuming equation of mathematical physics describing waves in shallow water.
This branch of science is attractive because it is one which revives the interest in the basic principles of mathematics, a beautiful formula.

Contents:

Readership: Applied mathematicians and mathematical physicists.

Review of the first edition:

"There is a bibliography of 112 items. This book is pedagogically written and is highly recommended for its detailed description of the resolvent method for soliton equations."
