For the past several decades, the study of free boundary problems has been a very active subject of research occurring in a variety of applied sciences. What these problems have in common is their formulation in terms of suitably posed initial and boundary value problems for nonlinear partial differential equations. Such problems arise, for example, in the mathematical treatment of the processes of heat conduction, filtration through porous media, flows of non-Newtonian fluids, boundary layers, chemical reactions, semiconductors, and so on. The growing interest in these problems is reflected by the series of meetings held under the title "Free Boundary Problems: Theory and Applications" (Ox ford 1974, Pavia 1979, Durham 1978, Montecatini 1981, Maubuisson 1984, Irsee 1987, Montreal 1990, Toledo 1993, Zakopane 1995, Crete 1997, Chiba 1999). From the proceedings of these meetings, we can learn about the different kinds of mathematical areas that fall within the scope of free boundary problems. It is worth mentioning that the European Science Foundation supported a vast research project on free boundary problems from 1993 until 1999. The recent creation of the specialized journal Interfaces and Free Boundaries: Modeling, Analysis and Computation gives us an idea of the vitality of the subject and its present state of development. This book is a result of collaboration among the authors over the last 15 years.
Rezensionen / Stimmen
"The book contains some new unpublished results. It will appeal to researchers in partial differential equations, nonlinear analysis, and continuum mechanics."
-Zentralblatt Math
". . . very important and useful monograph . . . The book is addressed to pure or applied mathematicians at universities and in industry and also to graduate level students. All results are presented in a systematic and self-contained manner, precise proofs being usually sufficiently detailed. The topic makes the book appealing for any specialist interested in applications of energy methods for free boundary problems in nonlinear PDEs and fluid mechanics."
-Mathematical Reviews
"The book...is a well-done selection of the most powerful energy methods - some of them very recent - used in the study of free boundary problems in nonlinear partial differential equations. Clearly and concisely written and containing a plenty of examples and applications, this monograph is of interset for all those mathematicians, or applied mathematicians, working in Partial Diffferential Equations, Nonlinear Analysis and Fluid Mechanics, physicists and engineers."
