Relativistic Many-Body Theory and Statistical Mechanics

In 1941, E.C.G. Stueckelberg wrote a paper, based on ideas of V. Fock, that established the foundations of a theory that could covariantly describe the classical and quantum relativistic mechanics of a single particle. Horwitz and Piron extended the applicability of this theory in 1973 (to be called the SHP theory) to the many-body problem. It is the purpose of this book to explain this development and provide examples of its applications. We first review the basic ideas of the SHP theory, both classical and quantum, and develop the appropriate form of electromagnetism on this dynamics. After studying the two body problem classically and quantum mechanically, we formulate the N-body problem. We then develop the general quantum scattering theory for the N-body problem and prove a quantum mechanical relativistically covariant form of the Gell-Mann-Low theorem. The quantum theory of relativistic spin is then developed, including spin-statistics, providing the necessary apparatus for Clebsch-Gordan additivity, and we then discuss the phenomenon of entanglement at unequal times. In the second part, we develop relativistic statistical mechanics, including a mechanism for stability of the off-shell mass, and a high temperature phase transition to the mass shell. Finally, some applications are given, such as the explanation of the Lindneret alexperiment, the proposed experiment of Palacios et al which should demonstrate relativistic entanglement (at unequal times), the space-time lattice, low energy nuclear reactions and applications to black hole physics.
Brazilian Jiu-Jitsu: Theory and Technique
Автор: Gracie Renzo, Gracie Royler, Danaher John
Год издания:
During the last decade, the martial arts world has looked to innovative mixed martial arts competitions such as the Ultimate Fighting Championship to determine which fighting style is the best. These contests have repeatedly shown the grappling style of martial arts, headed by Brazilian jiu-jitsu, to dominate. The Brazilian jiu-jitsu style stems from the premise, garnered from analysis of actual street fights, that the outcome of any fight is decided on the ground. While most martial arts deal only with the initial punching and kicking stages of combat, Brazilian jiu-jitsu concentrates on ground combat. This guide shows how to use Brazilian jiu-jitsu to increase combat effectiveness. Photographs and step-by-step instructions show how to master the techniques used in this exciting new form of combat.
Renzo Gracie, a two-time world Abu Dhabi submission jiu-jitsu champion, two-time Brazilian national champion, World Combat champion, and Martial Arts Reality Superfight champion, teaches Brazilian jiu-jitsu at an elite martial arts academy. Royler Gracie has competed in the Black Belt ranks for 20 years, winning the world title four times and the Abu Dhabi world submission championship for two consecutive years. They live in New York City.
Theory and practical aspects of Internationa settlements. Economic cooperation

Год издания:
As part of the dynamics of international economic cooperation by the need for mutual settlement operations, so the problem of organization of settlements is an important place for the economically active subjects, especially in a globalized economic space in the functioning of transnational structures and scale of the export, import and international financial transactions. In agreeing on the order of calculations, the participants determined the form of payment in order to fulfill the financial obligations of the agreement – regulated by means of voluntary compliance through a credit institution liabilities, characterized by specific features on the order of transfer of funds to the account, a certain kind of settlement document, as well as office procedures. The source of payment relations is the need to have one contractor expressed in the appropriate disposition, the other in shortage. This relationship gives rise as a consequence of the relationship with the lending institution. Need to accession will intensify in the subjects of international payment relationship.
