p-adic numbers play a very important role in modern number theory, algebraic geometry and representation theory. Lately p-adic numbers have attracted a great deal of attention in modern theoretical physics as a promising new approach for describing the non-Archimedean geometry of space-time at small distances.This is the first book to deal with applications of p-adic numbers in theoretical and mathematical physics. It gives an elementary and thoroughly written introduction to p-adic numbers and p-adic analysis with great numbers of examples as well as applications of p-adic numbers in classical mechanics, dynamical systems, quantum mechanics, statistical physics, quantum field theory and string theory.Contents:Analysis on the Field p-Adic Numbers:The Field of p-Adic NumbersAnalytic FunctionsAdditive and Multiplicative CharactersIntegration TheoryThe Gaussian IntegralsGeneralized FunctionsConvolution and the Fourier TransformationHomogeneous Generalized FunctionsPseudo-Differential Operators on the Field of p-Adic Numbers:The Operator D?p-Adic Schrodinger Operatorsp-Adic Quantum Theory:p-Adic Quantum MechanicsSpectral Theory in p-Adic Quantum MechanicsWeyl Systems.
