This book focuses on unstable systems both from the classical and the quantum mechanical points of view and studies the relations between them. The first part deals with quantum systems. Here the main generally used methods today, such as the Gamow approach, and the Wigner-Weisskopf method, are critically discussed. The quantum mechanical Lax-Phillips theory developed by the authors, based on the dilation theory of Nagy and Foias and its more general extension to approximate semigroup evolution is explained. The second part provides a description of approaches to classical stability analysis and introduces geometrical methods recently developed by the authors, which are shown to be highly effective in diagnosing instability and, in many cases, chaotic behavior. It is then shown that, in the framework of the theory of symplectic manifolds, there is a systematic algorithm for the construction of a canonical transformation of any standard potential model Hamiltonian to geometric form, making accessible powerful geometric methods for stability analysis in a wide range of applications.
WHEN in the future historians examine the second half of the twentieth century, they will no doubt identify the accelerated inter-nationalization of production as a landmark comparable with the Industrial Revolution. In this process multinational enterprises have been leading actors in the past twenty-five years and are certain to continue to be so in the next quarter-century. In 1975 the sales of the Western multinational corporations represented one-fifth of the Gross National Product of all capitalist countries. If their growth is maintained at the same rate as over the period 195o-75, by the end of the century this share will be nearly one-half and the whole capitalist economy may very well be dominated by some 200 giant corporations of which three-quarters may be American-based.
Providing a cutting-edge profile of research progress in this important field of study, Cholinergic Mechanisms: Function and Dysfunction contains a compilation of the proceedings of the Eleventh ISCM, held in St. Moritz, May 2002. Bringing together 250 contributors from 30 countries, the book presents a comprehensive picture of the cholinergic field. It provides a survey of current understanding of molecular, pharmacological, toxicological, behavioral, and clinical aspects of the cholinergic system. This volume offers a state-of-the-art account of progress in the field from the molecule in the test tube through the cell and the synapse, to the organism and the patient.
