Summary Note This book is concerned with the study in two dimensions of stationary solutions of u? of a complex valued Ginzburg-Landau equation involving a small parameter ?. Such problems are related to questions occurring in physics, e.g., phase transition phenomena in superconductors and superfluids. The parameter ? has a dimension of a length which is usually small.? Thus, it is of great interest to study the asymptotics as ? tends to zero. One of the main results asserts that the limit u-star of minimizers u? exists. Moreover, u-star is smooth except at a finite number of points called defects or vortices in physics. The number of these defects is exactly the Brouwer degree ? or winding number ? of the boundary condition. Each singularity has degree one ? or as physicists would say, vortices are quantized. The singularities have infinite energy, but after removing the core energy we are lead to a concept of finite renormalized energy.? The location of the singularities is completely determined by minimizing the renormalized energy among all possible configurations of defects.? The limit u-star can also be viewed as a geometrical object.? It is a minimizing harmonic map into S1?with prescribed boundary condition g.? Topological obstructions imply that every map u into S1?with u = g on the boundary must have infinite energy.? Even though u-star has infinite energy, one can think of u-star as having ?less? infinite energy than any other map u with u = g on the boundary. The material presented in this book covers mostly original results by the authors.? It assumes a moderate knowledge of nonlinear functional analysis, partial differential equations, and complex functions.? This book is designed for researchers and graduate students alike, and can be used as a one-semester text. ?The present softcover reprint is designed to make this classic text available to a wider audience. "...the book gives a very stimulating account of an interesting minimization problem. It can be a fruitful source of ideas for those who work through the material carefully." - Alexander Mielke, Zeitschrift f?r angewandte Mathematik und Physik 46(5).:
