Opis: Dispersion Decay and Scattering Theory - Elena Kopylova, Alexander Komech

Thoroughly classroom tested, this book applies scattering theory methods to modern problems within a variety of areas in advanced mathematics, quantum physics, and mathematical physics. It features the application of functional analysis, complex analysis, and theory of distributions for a comprehensive treatment of problems in mathematical physics and covers the Agmon-Jensen-Kato theory, along with eigenvalues, Klein-Gordon, and wave equations. Filled with exercises, hints, and explanatory figures throughout, this book will prove invaluable for students and professionals looking to expand their knowledge of scattering theory and partial differential equations.List of Figures xiii Foreword xv Preface xvii Acknowledgments xix Introduction xxi 1 Basic Concepts and Formulas 1 1 Distributions and Fourier transform 1 2 Functional spaces 3 2.1 Sobolev spaces 3 2.2 AgmonSobolev weighted spaces 4 2.3 Operatorvalued functions 5 3 Free propagator 6 3.1 Fourier transform 6 3.2 Gaussian integrals 8 2 Nonstationary Schrodinger Equation 11 4 Definition of solution 11 5 Schrodinger operator 14 5.1 A priori estimate 14 5.2 Hermitian symmetry 14 6 Dynamics for free Schrodinger equation 15 7 Perturbed Schrodinger equation 17 7.1 Reduction to integral equation 17 7.2 Contraction mapping 19 7.3 Unitarity and energy conservation 20 8 Wave and scattering operators 22 8.1 Moller wave operators.
