Spectral Methods in Surface Superconductivity
Av Søren Fournais, Bernard Helffer
Inbunden, 2010
550 kr
Lägg i varukorg
During the past decade, the mathematics of superconductivity has been the subject of intense activity. This book examines in detail the nonlinear Ginzburg–Landau functional, the model most commonly used in the study of superconductivity. Specifically covered are cases in the presence of a strong …

Bernard Helffer's graduate-level introduction to the basic tools in spectral analysis is illustrated by numerous examples from the Schrödinger operator theory and various branches of physics: statistical mechanics, superconductivity, fluid mechanics and kinetic theory. The later chapters also …
Hypoelliptic Estimates and Spectral Theory for Fokker-Planck Operators and Witten Laplacians
Av Francis Nier, Bernard Helffer
Häftad, 2005
551 kr
Lägg i varukorg
There has recently been a renewal of interest in Fokker-Planck operators, motivated by problems in statistical physics, in kinetic equations, and differential geometry. Compared to more standard problems in the spectral theory of partial differential operators, those operators are not self-adjoint …

Semi-Classical Analysis for the Schrodinger Operator and Applications
E-bok, 2006
367 kr
Lägg i varukorg
This introduction to semi-classical analysis is an extension of a course given by the author at the University of Nankai. It presents for some of the standard cases presented in quantum mechanics books a rigorous study of the tunneling effect, as an introduction to recent research work. The book …

Pseudo-Differential Operators
Quantization and Signals
Av Hans G. Feichtinger, Bernard Helffer m. fl.
Häftad, 2008
496 kr
Lägg i varukorg
Pseudo-differential operators were initiated by Kohn, Nirenberg and Hörmander in the sixties of the last century. Beside applications in the general theory of partial differential equations, they have their roots also in the study of quantization first envisaged by Hermann Weyl thirty years …

SEMICLASSICAL ANALYSIS, WITTEN LAPLACIANS, AND STATISTICAL MECHANICS
Inbunden, 2002
976 kr
Lägg i varukorg
This important book explains how the technique of Witten Laplacians may be useful in statistical mechanics. It considers the problem of analyzing the decay of correlations, after presenting its origin in statistical mechanics. In addition, it compares the Witten Laplacian approach with other …
