    Lie Groups and Algebraic Groups

    Lie Groups and Algebraic Groups by Arkadij L. Onishchik , Ernest B. Vinberg
    English | PDF | 1990 | 347 Pages | ISBN : 3642743366 | 45.7 MB

    This book is based on the notes of the authors' seminar on algebraic and Lie groups held at the Department of Mechanics and Mathematics of Moscow University in 1967/68. Our guiding idea was to present in the most economic way the theory of semisimple Lie groups on the basis of the theory of algebraic groups. Our main sources were A. Borel's paper [34], C. ChevalIey's seminar [14], seminar "Sophus Lie" [15] and monographs by C. Chevalley [4], N. Jacobson [9] and J-P. Serre [16, 17]. In preparing this book we have completely rearranged these notes and added two new chapters: "Lie groups" and "Real semisimple Lie groups". Several traditional topics of Lie algebra theory, however, are left entirely disregarded, e.g. universal enveloping algebras, characters of linear representations and (co)homology of Lie algebras. A distinctive feature of this book is that almost all the material is presented as a sequence of problems, as it had been in the first draft of the seminar's notes. We believe that solving these problems may help the reader to feel the seminar's atmosphere and master the theory. Nevertheless, all the non-trivial ideas, and sometimes solutions, are contained in hints given at the end of each section. The proofs of certain theorems, which we consider more difficult, are given directly in the main text. The book also contains exercises, the majority of which are an essential complement to the main contents.

    Fluid Dynamics of Viscoelastic Liquids

    Fluid Dynamics of Viscoelastic Liquids

    Fluid Dynamics of Viscoelastic Liquids by Daniel D. Joseph
    English | PDF | 1990 | 772 Pages | ISBN : 0387971556 | 47.8 MB

    This book is about two special topics in rheological fluid mechanics: the elasticity of liquids and asymptotic theories of constitutive models. The major emphasis of the book is on the mathematical and physical consequences of the elasticity of liquids; seventeen of twenty chapters are devoted to this. Constitutive models which are instantaneously elastic can lead to some hyperbolicity in the dynamics of flow, waves of vorticity into rest (known as shear waves), to shock waves of vorticity or velocity, to steady flows of transonic type or to short wave instabilities which lead to ill-posed problems. Other kinds of models, with small Newtonian viscosities, give rise to perturbed instantaneous elasticity, associated with smoothing of discontinuities as in gas dynamics. There is no doubt that liquids will respond like elastic solids to impulses which are very rapid compared to the time it takes for the molecular order associated with short range forces in the liquid, to relax. After this,all liquids look viscous with signals propagating by diffusion rather than by waves. For small molecules this time of relaxation is estimated as lQ-13 to 10-10 seconds depending on the fluids. Waves associated with such liquids move with speeds of 1 QS cm/s, or even faster. For engineering applications the instantaneous elasticity of these fluids is of little interest; the practical dynamics is governed by diffusion, ·say, by the Navier-Stokes equations. On the other hand, there are other liquids which are known to have much longer times of relaxation.

    Computational Mechanics of Nonlinear Response of Shells

    Computational Mechanics of Nonlinear Response of Shells by Wilfried B. Krätzig, Eugenio Oñate
    English | PDF | 1990 | 410 Pages | ISBN : 3642840477 | 40.1 MB

    Shell structures and their components are applied in many engineering fields. Designers are attaching ever increasing importance to nonlinear responses such as large deformations, instabilities and nonlinear material properties in their design analysis. This volume presents a careful selection of papers from the ICES '88 Conference covering various aspects of nonlinear shell responses.

    Direct and Inverse Problems: Potentials in Quantum Scattering

    Direct and Inverse Problems: Potentials in Quantum Scattering by Boris N. Zakhariev , Allina A. Suzko
    English | PDF | 1990 | 234 Pages | ISBN : 3540524843 | 21.5 MB

    Rapid progress in quantum theory brings us new important results which are often not immediately clear to all who need them. But fortunately, this is also followed by simplifications and unifications of our previous concepts. The inverse problem method ("The most beautiful idea of the XX-th century" - Zakharov et aI., 1980) has just both these aspects. It is rather astonishing that it took 50 years after the foundation of quantum mechanics for the creation of the "pictures" showing the direct connection of obser­ vables with interactions. Recently, illustrations of this type began to appear in the literature (e. g., how potentials are deformed with thc shift of one energy level or change of some resonance reduced width). Although they are transparent to those studying the quantum world and can be included within the necessary elements of quantum literacy, they are still largely unknown even to many specialists. For the first time, the most interesting of these pictures enriching our quantum intuition are col­ lected here and placed at your disposal. The readers of this monograph have the advantage of getting the latest information which became available after the publication of the Russian edition. It has been incor­ porated here in the simplest presentation possible. For example, new sections con­ cerning exactly solvable models, including the multi-channel, multi-dimensional ones and with time dependent potentials have been added. The first attempts in solving the three-body inverse problem are also mentioned.

    Vertebrate Flight: Mechanics, Physiology, Morphology, Ecology and Evolution

    Vertebrate Flight: Mechanics, Physiology, Morphology, Ecology and Evolution by Ulla M. Norberg
    English | PDF | 1990 | 304 Pages | ISBN : 3642838502 | 33.6 MB

    It has been great fun to write this book, even though it has taken longer than planned, and occasionally been exasperating. The most difficult problem was deciding what to exclude among so many interesting things, because the available material usually exceeded the space. Because a book like this covers so many aspects, each component must be limited. This book is intended for graduate and undergraduate students as well as professional scientists who want to work with animal flight or to gain some insight into flight mechanics, aerodynamics, energetics, physiology, morpho­ logy, ecology and evolution. My aim has not been to give the whole mathe­ matical explanation of flight, but to provide an outline and summary of the main theories for the understanding of how aerofoils respond to an airflow. I also hope to give the reader some insight into how flight morphology and the various wing shapes have evolved and are adapted to different ecological niches and habitats.

    Statistical Theory of Heat: Nonequilibrium Phenomena

    Statistical Theory of Heat: Nonequilibrium Phenomena

    Statistical Theory of Heat: Nonequilibrium Phenomena by Wilhelm Brenig
    English | PDF | 1989 | 297 Pages | ISBN : 364274687X | 31.2 MB

    This text on the statistical theory of nonequilibrium phenomena grew out of lecture notes for courses on advanced statistical mechanics that were held more or less regularly at the Physics Department of the Technical University in Munich. My aim in these lectures was to incorporate various developments of many-body theory made during the last 20-30 years, in particular the correlation function approach, not just as an "extra" alongside the more "classical" results; I tried to use this approach as a unifying concept for the presentation of older as well as more recent results. I think that after so many excellent review articles and advanced treatments, correlation functions and memory kernels are as much a matter of course in nonequilibrium statistical physics as partition functions are in equilibrium theory, and should be used as such in regular courses and textbooks. The relations between correlation functions and earlier vehicles for the formulation of nonequilibrium theory such askinetic equations, master equations, Onsager's theory, etc. , are discussed in detail in this volume. Since today there is growing interest in nonlinear phenomena I have included several chapters on related problems. There is some nonlinear response theory, some results on phenomenological nonlinear equations and some microscopic applications of the nonlinear response formalism. The main focus, however, is on the linear regime.

    An Introduction to Hilbert Space and Quantum Logic

    An Introduction to Hilbert Space and Quantum Logic

    An Introduction to Hilbert Space and Quantum Logic by David W. Cohen
    English | PDF | 1989 | 159 Pages | ISBN : 1461388430 | 6.7 MB

    Historically, nonclassical physics developed in three stages. First came a collection of ad hoc assumptions and then a cookbook of equations known as "quantum mechanics". The equations and their philosophical underpinnings were then collected into a model based on the mathematics of Hilbert space. From the Hilbert space model came the abstaction of "quantum logics". This book explores all three stages, but not in historical order. Instead, in an effort to illustrate how physics and abstract mathematics influence each other we hop back and forth between a purely mathematical development of Hilbert space, and a physically motivated definition of a logic, partially linking the two throughout, and then bringing them together at the deepest level in the last two chapters. This book should be accessible to undergraduate and beginning graduate students in both mathematics and physics. The only strict prerequisites are calculus and linear algebra, but the level of mathematical sophistication assumes at least one or two intermediate courses, for example in mathematical analysis or advanced calculus. No background in physics is assumed.

    Vibration and Coupling of Continuous Systems: Asymptotic Methods

    Vibration and Coupling of Continuous Systems: Asymptotic Methods by J. Sanchez Hubert, E. Sanchez Palencia
    English | PDF | 1989 | 453 Pages | ISBN : 3642737846 | 51.1 MB

    Real problems concerning vibrations of elastic structures are among the most fascinating topics in mathematical and physical research as well as in applications in the engineering sciences. This book addresses the student familiar with the elementary mechanics of continua along with specialists. The authors start with an outline of the basic methods and lead the reader to research problems of current interest. An exposition of the method of spectra, asymptotic methods and perturbation is followed by applications to linear problems where elastic structures are coupled to fluids in bounded and unbounded domains, to radiation of immersed bodies, to local vibrations, to thermal effects and many more.

    It is propitious that the 25th year of publication of the International Journal of Fracture should coincide with the opportunity to support the recognition by the Society of Engineer­ ing Science of the 65th birthday of the Founding Editor-in-Chief, Professor M.L. Williams. At its 24th Annual Meeting at the University of Utah in September 1987, the Organizing Committee of the Society chose to honor Professor Williams by reserving several sessions for contributions from his colleagues working in the mechanics of fracture and associated mechanical property-structure relationships. We are therefore pleased to welcome Professor E.S. Folias, Professor of Mechanical Engineering, University of Utah, and a member of the Editorial Committee as the Guest Editor for the first three issues of Volume 39 of the Journal. We have also noted that the University of Utah was one of the three homes for the Journal, sandwiched between the original home at the California Institute of Technology in 1965 and its current location at the University of Pittsburgh. In observing these dual anniversaries, the publishers not only enthusiastically support the presentation of these special papers, but also wish to extend to Professor Williams our own best wishes on his personal anniversary, and to thank him and all the authors, reviewers, and particularly M.e. Williams, J.L. Swedlow and the Regional Editors for their respective contributions as we observe this 25th milestone.

    Poesie dall'ospedale psichiatrico - Bruno Osimo
    Italiano | 2025 | 89 Pages | ISBN: 8898467605 | EPUB | 180.21 KB

    L'autore è ricoverato in ospedale psichiatrico in un non meglio precisato paese baltico da diversi anni. Dai versi trapelano sia le terapie a cui è sottoposto (compreso uso di alcol non consentito dalle autorità sanitarie), sia le relazioni col personale, infermiere e infermieri, il rapporto con gli animali domestici (è una comunità controllata, con sperimentazione di pet therapy). I versi, sull'onda tra delirio e poesia, tra realtà e immaginazione, tra prescrizione e trasgressione, sono suggestivi dell'atmosfera unica che si respira all'interno dell'istituzione manicomiale o postmanicomiale.

    Fa impressione constatare riga dopo riga la nostra ignoranza: tutti noi abbiamo sentito parlare soprattutto delle purghe staliniane, ma invece qui già nel ventennio 1917-1936 assistiamo alla teorizzazione e alla messa in pratica leniniana di questo sistema disumano. E i principali prigionieri in tutto questo periodo non sono i fascisti o gli aristocratici, ma i socialisti e i socialdemocratici, i socialrivoluzionari, i menscevichi, perfino gli ecclesiastici, ossia tutto quello che oggi chiameremmo «campo largo» e che farebbe parte del versante democratico del panorama politico.

    Ah, che dolcezza la costa bretone in una giornata mite e spensierata, soprattutto se è la costa di granito rosa, il cui bagliore soprannaturale ammalia e incanta. O almeno, questo è ciò che dovrebbe pensare anche il commissario Georges Dupin, finalmente in vacanza al mare, a Trégastel, con Claire, la sua compagna. La vacanza piú lunga della sua vita lavorativa.
