Brand: Brand: SpringerVerlag

The contributions in this volume focus on the use of general connectivity (unstructured) adaptive meshes for Lagrangian calculations but contain a substantial amount of material on Euler and arbitrary LagrangeEuler techniques as well. Contributions on the smooth particle hydrodynamics method and on deterministic vortex methods broaden the scope of the material and allow comparisons of different, though allied, techniques to be made. The format of the conference was designedto optimize the interaction among the attendees. An edited version of roundtable discussions is included in these proceedings.

Group Theoretical Methods in Physics: Proceedings of the XVII International Colloquium Held at Moscow, Ussr, 49 June 1990 (INTERNATIONAL COLLOQUIUM ... THEORETICAL METHODS IN PHYSICS: PROCEEDINGS)
Lowest new price: $72.66
Lowest used price: $3.86
List price: $108.00
Author: V. V. Dodonov

This volume contains review talks and a small selection of the research papers presented at the world's most distinguished conference on group theoretical methods in physics. The papers are devoted to such topics as spectrum generating groups, quantum groups, coherent states, and geometric aspects of group representations. The methods apply to nuclear physics, quantum mechanics, ordinary and supersymmetric linear and non linear differential equations, geometry, and noncommutative geometry. The book addresses theoretical physicists, especially those in research.


Differential Geometry, Group Representations, and Quantization (Lecture Notes in Physics, Vol 379)
Lowest used price: $21.35
List price: $44.95
Author: J.D. Hennig

Differential geometry and analytic group theory are among the most powerful tools in mathematical physics. This volume presents review articles on a wide variety of applications of these techniques in classical continuum physics, gauge theories, quantization procedures, and the foundations of quantum theory. The articles, written by leading scientists, address both researchers and grad uate students in mathematics, physics, and philosophy of science.

Author: A. V. GaponovGrekhov

In the dynamics of mankind one can trace out a path of contemplation about the "world", leading from early speculations to today's natural sciences. The endeavour to understand how nature works has led to the construction, still in progress, of an abstract building of great com plexity. To the uninitiated it may look more like a scurrilous sculpture resting on many legs, among them such peculiar ones as probability, relativity, quantum mechanics .... At times problems with the stabil ity of the building or sculpture arise: known facts that won't fit and can no longer be ignored start to undermine the foundations. Then new footings are thought of, constructed and finally cast. In fact, the undermining and casting is often done in one step. This process has already been repeated many times and will un doubtedly repeat itself again and again. At present, one recognizable footing under construction goes by the name of "chaos theory". Physi cists seem to like the word chaos. When they came to recognize that the air is not just empty space but an obviously indescribable dance of myriads of molecules they called that "chaos". What else would fit? In the course of time the name was simplified to "gas". Thus the word chaos became free to serve for the next upsetting experience. That arose in the context of nonlinear dynamical systems, where peculiar motions were detected, ones seemingly beyond human comprehension.

Analysis and Continuum Mechanics: A Collection of Papers Dedicated to J. Serrin on His Sixtieth Birthday
Lowest used price: $10.85
List price: $107.00
Author: S. S. Antman

The 39 papers in this collection are devoted mostly to the exact mathematical analysis of problems in continuum mechanics, but also to problems of a purely mathematical nature mainly connected to partial differential equations from continuum physics. All the papers are dedicated to J. Serrin and were originally published in the "Archive of Rational Mechanics and Analysis".

Theoretical Physics on the Personal Computer/Book and Disk (English and German Edition)
Lowest new price: $49.50
Lowest used price: $6.41
List price: $49.50
Author: Erich W. Schmid

Theoretical Physics on the Personal Computer is a very successful, novel, easytocomprehend, and wellstructured text, ideal as an introduction to problemsolving with computers for advanced undergraduate students in physics and applied mathematics. The required Fortran 77 software for this book is included on a floppy disk. It has been designed for the IBM PC/XT, PC/AT, and PS/2, and for compatible computers such as the Siemens PCD2, etc., but it can also be run on mainframes. The second edition has not only been corrected and updated; with the new software the user can work with Microsoft Fortran (with or without a mathematical coprocessor) or the IBM Profort compiler (with coprocessor).


The Vector Coherent State Method and Its Application to Problems of Higher Symmetries (Lecture Notes in Physics)
Lowest new price: $29.95
Lowest used price: $74.90
List price: $29.95
Author: K. T. Hecht

These lectures review the recently developed vector coherent state method. The book is an excellent introduction to the field because of the many examples treated in detail, in particular those from nuclear and particle physics. These calculations will be welcomed by researchers and graduate students. The author reviews the concepts of coherent states of the Heisenberg algebra and shows then that the vector coherent state method maps the higher symmetry algebra into an ndimensional harmonic oscillator algebra coupled with a simple intrinsic symmetry algebra. The formulation involves some vector (or analogous higher symmetry) coupling of the intrinsic algebra with the ndimensional oscillator algebra, leading to matrix representations and Wigner coefficients of the higher symmetry algebra expressed in terms of simple calculable functions and recoupling coefficients for the simpler intrinsic algebra.
