BLACK HOLE UNIQUENESS THEOREMS VOL:6

相關熱銷的書籍推薦給您

This timely review provides a self-contained introduction to the mathematical theory of stationary black holes and a self-consistent exposition of the corresponding uniqueness theorems. The opening chapters examine the general properties of space-times admitting Killing fields and derive the Kerr-Newman metric. Heusler emphasizes the general features of stationary black holes, the laws of black hole mechanics, and the geometrical concepts behind them. Tracing the steps toward the proof of the "no-hair" theorem, he illustrates the methods used by Israel, the divergence formulas derived by Carter, Robinson and others, and finally the sigma model identities and the positive mass theorem. The book also includes an extension of the electro-vacuum uniqueness theorem to self-gravitating scalar fields and harmonic mappings. A rigorous textbook for graduate students in physics and mathematics, this volume offers an invaluable, up-to-date reference for researchers in mathematical physics, general relativity and astrophysics.

DESCRIPTION A one-stop reference to the major techniques for analyzing microwave planar transmission line structures The last two decades have seen important progress in the development of methods for the analysis of microwave and millimeter-wave passive structures, which contributed greatly to microwave integrated circuit design while also stimulating the development of new planar transmission lines. This timely and authoritative work introduces microwave engineers to the most commonly used techniques for analyzing microwave planar transmission line structures. Designed to be easily accessible to readers with only a fundamental background in electromagnetic theory, the book provides clear explanations of the theory and applications of Green's function, the conformal-mapping method, spectral domain methods, variational methods, and the mode-matching methods. Coverage for each method is self-contained and supplemented with problems and solutions as well as useful figures. In addition to providing detailed formulations of the methods under discussion, this highly practical book also demonstrates how to apply the principles of electromagnetic theory to the analysis of microwave boundary value problems, customize methods for specific needs, and develop new techniques. Analysis Methods for RF, Microwave, and Millimeter-Wave Planar Transmission Line Structures is an excellent working resource for anyone involved in the design and engineering of RF, microwave, and millimeter-wave integrated circuits.

【簡介】 A phase-locked loop (PLL) is a type of circuit with a range of important applications in telecommunications and computing. It generates an output signal with a controlled relationship to an input signal, such as an oscillator which matches the phases of input and output signals. This is a critical function in coherent communication systems, with the result that the theory and design of these circuits are essential to electronic communications of all kinds. Phase-Locked Loops: System Perspectives and Circuit Design Aspects provides a concise, accessible introduction to PLL design. It introduces readers to the role of PLLs in modern communication systems, the fundamental techniques of phase-lock circuitry, and the possible applications of PLLs in a wide variety of electronic communications contexts. The first book of its kind to incorporate modern architectures and to balance theoretical fundamentals with detailed design insights, this promises to be a must-own text for students and industry professionals. The book also features: Coverage of PLL basics with insightful analysis and examples tailored for circuit designers Applications of PLLs for both wireless and wireline systems Practical circuit design aspects for modern frequency generation, frequency modulation, and clock recovery systems Phase-Locked Loops is essential for graduate students and advanced undergraduates in integrated circuit design, as well researchers and engineers in electrical and computing subjects. 【目錄】 1 Introduction Part I Phase-Lock Basics 2 Linear Model and Loop Dynamics 3 Transient Response Part II System Perspectives 4 Frequency and Spectral Purity 5 Application Aspects Part III Building Circuits 6 PhaseDetector 7 Voltage-Controlled Oscillator 8 Frequency Divider Part IV PLL Architectures 9 Fractional-N PLL 10 Digital-Intensive PLL 11 Clock-and-Data Recovery PLL

Solutions and X-ray Non-3D Phase Structure Analysis of Soft Matter

Physics and Chemistry of Molecular Assemblies Most researchers would relate X-ray structure analysis to crystal structure analysis. A crystal is a state in which atoms or molecules are regularly arranged in three-dimensional space. However, some substances do not have 3D structures, but have 1D, 2D, 1D⊕1D, 2D⊕1D or 1D⊕1D⊕1D structures. Here the symbol ⊕ stands for direct sum in linear algebra and is different from ordinary sum +. For example, 2D⊕1D means the direct sum of a 2D subspace and an orthogonal 1D subspace, not 3D. In a previous book, Physics and Chemistry of Molecular Assemblies, published in April 2020, the author showed for the first time that molecular assemblies can be represented in a unified manner from such subspaces of linear algebra, and wrote the theory and method of X-ray structure analysis of the liquid crystal phase structures with the dimensional structure of 1D, 2D, 1D⊕1D, 2D⊕1D, and 1D⊕1D⊕1D. Furthermore, the X-ray liquid crystal structure analysis methods of 11 representative examples were concretely described. In addition, 110 X-ray data were posted as the end-of-chapter problems in Chapter 3. Using the methods developed by the author, these 110 problems can be solved in principle with a calculator, graph paper, a ruler, and a compass, although it takes time. However, when you use only a calculator, a graph paper, a ruler or a compass, it would probably take more than one year to analyze all the observed X-ray data in Chapter 3. Therefore, the author\'s research group has developed a computer program named "Bunseki-kun." By using this program, we can easily analyze the liquid crystal phase structures from the observed d spacings. Thus, when you use this program, you will be able to analyze the liquid crystal phase and other soft matter phase structures within 1/100th to 1/1000th of the time.
