Описание: This introduction to the theory of Sobolev spaces and Hilbert space methods in partial differential equations is geared toward readers of modest mathematical backgrounds. It offers coherent, accessible demonstrations of the use of these techniques in developing the foundations of the theory of finite element approximations. J. T. Oden is Director of the Institute for Computational Engineering & Sciences (ICES) at the University of Texas at Austin, and J. N. Reddy is a Professor of Engineering at Texas A&M University. They developed this essentially self-contained text from their seminars and courses for students with diverse educational backgrounds. Their effective presentation begins with introductory accounts of the theory of distributions, Sobolev spaces, intermediate spaces and duality, the theory of elliptic equations, and variational boundary value problems. The second half of the text explores the theory of finite element interpolation, finite element methods for elliptic equations, and finite element methods for initial boundary value problems. Detailed proofs of the major theorems appear throughout the text, in addition to numerous examples.
Описание: Geared toward research students in physics and chemistry, this text introduces the three main uses of group theory in quantum mechanics: (1) to label energy levels and the corresponding eigenstates; (2) to discuss qualitatively the splitting of energy levels, starting from an approximate Hamiltonian and adding correction terms; and (3) to aid in the evaluation of matrix elements of all kinds. "The theme," states author Volker Heine, "is to show how all this is achieved by considering the symmetry properties of the Hamiltonian and the way in which these symmetries are reflected in the wave functions." Early chapters cover symmetry transformations, the quantum theory of a free atom, and the representations of finite groups. Subsequent chapters address the structure and vibrations of molecules, solid state physics, nuclear physics, and relativistic quantum mechanics. A previous course in quantum theory is necessary, but the relevant matrix algebra appears in an appendix. A series of examples of varying levels of difficulty follows each chapter. They include simple drills related to preceding material as well as extensions of theory and further applications. The text is enhanced with 46 illustrations and 12 helpful appendixes.

Описание:
Written in response to a book on the origins of morality by his erstwhile friend Paul Ree, the three essays comprising The Genealogy of Morals -- all three advancing the critique of Christian morality set forth in Beyond Good and Evil -- are among Nietzsche's most sustained and cohesive work. In the first essay -- starting from a linguistic analysis of words such as -good, - -bad, - and -evil- -- Nietzsche sets up a contrast between what he calls -master- morality and -slave- morality and shows how strength and action have often been replaced by passivity and nihilism. The next essay, looking into the origins of guilt and punishment, shows how the concept of justice was born -- and how internalization of this concept led to the development of what people called -the soul.- In the third essay, Nietzsche dissects the meaning of ascetic ideals. It is not Nietzsche's intention to reject ascetic ideals, -slave- morality, or internalized values out of hand; his main concern is to show that culture and morality, rather than being eternal verities, are human-made. Whether or not you agree with all of his conclusions, his writing is of such clarity and brilliance that you will find reading The Genealogy of Morals nothing short of exhilarating.
Описание: Moral Realism is a systematic defence of the idea that there are objective moral standards. Russ Shafer-Landau argues that there are moral principles that are true independently of what anyone, anywhere, happens to think of them. His central thesis, as well as the many novel supporting arguments used to defend it, will spark much controversy among those concerned with the foundations of ethics.

Описание: This clear presentation of the most fundamental models of random phenomena employs methods that recognize computer-related aspects of theory. The text emphasizes the modern viewpoint, in which the primary concern is the behavior of sample paths. By employing matrix algebra and recursive methods, rather than transform methods, it provides techniques readily adaptable to computing with machines. Topics include probability spaces and random variables, expectations and independence, Bernoulli processes and sums of independent random variables, Poisson processes, Markov chains and processes, and renewal theory. Assuming some background in calculus but none in measure theory, the complete, detailed, and well-written treatment is suitable for engineering students in applied mathematics and operations research courses as well as those in a wide variety of other scientific fields. Many numerical examples, worked out in detail, appear throughout the text, in addition to numerous end-of-chapter exercises and answers to selected exercises.

Описание: Klemens von Klemperer traces the many efforts of the German Resistance to forge alliances with Hitler`s opponents outside Germany. He uncovers the activities and beliefs of individual members, the formation of Resistance policies, their relations with the intelligence agencies of the Allied powers, and finally assesses the Resistance`s influence on the agenda of post-war international relations.
