Specifically designed to introduce graduate students to the functional integration method in contemporary physics as painlessly as possible, the book concentrates on the conceptual problems inherent in the path integral formalism. Throughout, the striking interplay between stochastic processes, statistical physics and quantum mechanics comes to the fore, and all the methods of fundamental interest are generously illustrated by important physical examples.

"Quantum Gravitation" approaches the subject from the point of view of Feynman path integrals, which provide a manifestly covariant approach in which fundamental quantum aspects of the theory such as radiative corrections and the renormalization group can be systematically and consistently addressed. It is shown that the path integral method is suitable for both perturbative as well as non-perturbative studies, and is already known to offer a framework for the theoretical investigation of non-Abelian gauge theories, the basis for three of the four known fundamental forces in nature. The book thus provides a coherent outline of the present status of the theory gravity based on Feynman’s formulation, with an emphasis on quantitative results. Topics are organized in such a way that the correspondence to similar methods and results in modern gauge theories becomes apparent. Covariant perturbation theory are developed using the full machinery of Feynman rules, gauge fixing, background methods and ghosts. The renormalization group for gravity and the existence of non-trivial ultraviolet fixed points are investigated, stressing a close correspondence with well understood statistical field theory models. The final chapter addresses contemporary issues in quantum cosmology such as scale dependent gravitational constants and quantum effects in the early universe.

Topological restrictions. These are relevant to the understanding of the statistical properties of elementary particles and the entanglement phenomena in polymer physics and biophysics. The Chern-Simons theory of particles with fractional statistics (anyons) is introduced and applied to explain the fractional quantum Hall effect." "The relevance of path integrals to financial markets is discussed, and improvements of the famous Black-Scholes formula for option prices are developed which account for the fact that large market fluctuations occur much more frequently than in Gaussian distributions." --Book Jacket.

Traditionally, field theory is taught through canonical quantization with a heavy emphasis on high energy physics. However, the techniques of field theory are applicable as well and are extensively used in various other areas of physics such as consdensed matter, nuclear physics and statistical mechanics. The path integral approach brings out this feature most clearly. In this book, the path integral approach is developed in detail completely within the context of quantum mechanics. Subsequently, it is applied to various areas of physics.

MySearchLab provides students with a complete understanding of the research process so they can complete research projects confidently and efficiently. Students and instructors with an internet connection can visit www.MySearchLab.com and receive immediate access to thousands of full articles from the EBSCO ContentSelect database. In addition, MySearchLab offers extensive content on the research process itself—including tips on how to navigate and maximize time in the campus library, a step-by-step guide on writing a research paper, and instructions on how to finish an academic assignment with endnotes and bibliography. This engaging collection of readings presents a multifaceted view of contemporary gender relations. Using other inequalities such as race, class, and sexual orientation as a prism of difference, the readings present gender as it is situated in sexual, racial-ethnic, social class, physical abilities, age, and national citizenship contexts. In addition to articles about men, women, and sexual, and immigrant diversity, this reader also includes works on gender and globalization. The editors introduce this wide-ranging collection with a provocative analytical introduction that sets the stage for understanding gender as a socially constructed experience. Takes a sociological perspective on contemporary gender relations. Emphasizes the theme of difference or how other inequalities such as race, class, or age affect our gendered experiences. Presents a discussion of women's and men's issues. Includes articles on international and transnational factors in addition to the articles on U.S. gender relations. For anyone interested in Sociology of Gender, Women's Studies, Gender Roles, Sociology of Women, Women in Society, Race, Class, and Gender, Diversity, Feminist Theory, and Social Inequality.

Path Integrals in Physics: Volume I, Stochastic Processes and Quantum Mechanics presents the fundamentals of path integrals, both the Wiener and Feynman type, and their many applications in physics. Accessible to a broad community of theoretical physicists, the book deals with systems possessing a infinite number of degrees in freedom. It discusses the general physical background and concepts of the path integral approach used, followed by a detailed presentation of the most typical and important applications as well as problems with either their solutions or hints how to solve them. It describes in detail various applications, including systems with Grassmann variables. Each chapter is self-contained and can be considered as an independent textbook. The book provides a comprehensive, detailed, and systematic account of the subject suitable for both students and experienced researchers.
