Résumé
In keeping with the spirit of harmonic analysis, the guiding theme of the book is to illustrate how the powerful techniques of time-frequency analysis - based on the decomposition of functions and operators in terms of the so-called Gabor wave packets - can be successfully applied to mathematical path integrals, leading to remarkable results and paving the way to a fruitful interaction.
This monograph intends to build a bridge between the communities of people working in time-frequency analysis and mathematical/theoretical physics, and to provide an exposition of the present novel approach along with its basic toolkit. Having in mind a researcher or a Ph.D. student as reader, we collected in Part I the necessary background, in the most suitable form for our purposes, following a smooth pedagogical pattern. Then Part II covers the analysis of path integrals, reflecting the topics addressed in the research activity of the authors in the last years.
- Part I Elements of Gabor Analysis.
- Basic Facts of Classical Analysis. - The Gabor Analysis of Functions. - The Gabor Analysis of Operators. - Semiclassical Gabor Analysis.
- Part II Analysis of Feynman Path Integrals.
- Pointwise Convergence of the Integral Kernels. - Convergence in L(L2) - Potentials in the Sjoestrand Class. - Convergence in L(L2) - Potentials in Kato-Sobolev Spaces. - Convergence in the Lp Setting.
