Dieses Buch ist eine Darstellung des Mathematikstoffs für Physiker, die etwa einem vierstündigen Vorlesungsprogramm von vier Semestern entspricht. Darüber hinaus enthält es ein weiterführendes Kapitel über unbeschränkte Operatoren, wie sie in der Quantenmechanik auftreten. Das Buch umfaßt neben linearer Algebra, Funktionentheorie und klassischen Gebieten auch Distributionen, Anfangs-, Randwert- und Anfangsrandwertprobleme für Differentialgleichungen und eine Einführung in die Funktionalanalysis. Ein Ziel ist es, auch neuere Methoden der Mathematik, die in die Physik Eingang gefunden haben, vorzustellen. So werden der Kalkül der Differentialformen und seine Anwendungen, Distributionen, Fundamentallösungen von Differentialgleichungen, Hilbert-Räume und Operatoren hier behandelt. Zahlreiche Erläuterungen, Beispiele sowie Übungsaufgaben und ihre Lösungen unterstützen die Lektüre und ergänzen den Text.

Als Grenztheorie der Quantenmechanik besitzt die klassische Dynamik einen grossen Formenreichtum, vom gut berechenbaren (integablen) bis zum chaotischen (mischenden) Verhalten. Immer ausgehend von interessanten Beispielen in der Physik bietet das vorliegende Buch nicht nur eine gelungene Auswahl grundlegender Themen, sondern auch einen Einstieg in viele aktuelle Forschungsgebiete aus dem Bereich der klassischen Mechanik. Durch den didaktisch geschickten Aufbau und die konzentrierten Anhänge ist die Darstellung in sich geschlossen und setzt lediglich Kenntnisse der Grundvorlesungen in Mathematik voraus. Ein Höhepunkt des Buches ist die Darstellung der KAM-Theorie  (Kolmogorov-Arnold-Moser Theorie).

This textbook is based on lecture notes that the author delivered at Qiuzhen College (Tsinghua University), a Chinese institution known for its exceptionally talented mathematics students. The book's intended audience shapes its character. It introduces Statistical Mechanics from the ground up, offering a fully self-contained presentation that aims for mathematical precision. It distinguishes rigorous results from controlled approximations and provides physical insights into phenomena. Despite its concise nature (suited for a one-semester basic course), this book covers several topics typically not found in introductory texts. These include Shannon's information-theoretic interpretation of entropy, the gauge approach to order-disorder duality in the Ising model, the Yang-Lee theory, and the quantum dissipation-fluctuation theorem. Additionally, it explores frustrated and quenched systems, including an introduction to the celebrated Parisi solution of the Sherrington-Kirkpatrick model of spin glasses. The path integral formalism is extensively discussed from various perspectives to suit different applications. Chapter 2 approaches path integrals through the Feynman-Kac formula and second quantization. In Chapter 5, they are examined within the context of effective field theories like Landau-Ginzburg theory, while Chapter 6 delves into their connection with Brownian motion, Langevin stochastic differential equations, and Fokker-Planck diffusion PDEs. The book also explores the relationship between stochastic processes and supersymmetry. Various techniques for computing path integrals, especially functional determinants, are introduced throughout the relevant chapters, offering the most suitable computational tools for each application.

This book is about the Random Field Ising Model (RFIM) – a paradigmatic spin model featuring a frozen disordering field. The focus is on the second-order phase transition between the paramagnetic and ferromagnetic phases, and the associated critical exponents. The book starts by summarizing the current knowledge about the RFIM from experiments, numerical simulations and rigorous mathematical results. It then reviews the classic theoretical works from the 1970’s which suggested a property of dimensional reduction – that the RFIM critical exponents should be the same as for the ordinary, non-disordered, Ising model of lower dimensionality, and related this an emergent Parisi-Sourlas supersymmetry. As is now known, these remarkable properties only hold when the spatial dimensionality of the model is larger than a critical dimension. The book presents a method to estimate the critical dimension, using standard tools such as the replica trick and perturbative renormalization group, whose result is in agreement with the numerical simulations. Some more elementary steps in the derivations are left as exercises for the readers. This book is of interest to researchers, PhD students and advanced master students specializing in statistical field theory.

Knowledge of and skill in physics are essential foundations for studies in science and engineering. This book offers students an introduction to the basic concepts and principles of physics. It covers various topics specifically related to physical mechanics, the properties of matter, and heat. Each chapter begins with a summary of concepts, principles, definitions, and formulae to be discussed, as well as ending with problems and solutions that illustrate the specific topic. Steps are detailed to help build reasoning and understanding. There are 300 worked problems and 100 exercises in the book, as well as 306 figures to help the reader visualize the processes being addressed. Computer calculations and solutions are carried out using wxMaxima to give insight and help build computational skills. The book is aimed at first-year undergraduate students studying introductory physics, and would also be useful for physics teachers in their instruction, particularly the exercises at the end of each chapter.
