摘要

The Ginzburg-Landau model for superconductivity stands as a remarkable theory, capturing and at least partially explaining, as it does, a wide array of observed behaviors of superconductors. This is achieved through minimization of a relatively simple-looking energy involving the interplay between a complex-valued wave function whose square modulus measures the density of the so-called Cooper pairs carrying the super-current and a vector-valued potential whose curl represents the magnetic field induced by the superconductor in response to applied fields. Introduced in 1950 as a phenomenologi-cal macroscopic theory, an acknowledgment of its impact within the physics community came with the awarding of the 2003 Nobel Prize to Vi-taly Ginzburg. Within the mathematics community, contributions came sporadically during the 1970's and 80's but then exploded in the 1990's and the last decade. In the book under review, the authors collect and present a sizable sector of this mathematical progress.
