The breakup of the Soviet Union left a cold war nuclear legacy consisting of tens of thousands of nuclear weapons and a sprawling infrastructure for their production and maintenance.The Soviet Nuclear Weapon Legacy examines the fate of this vast nuclear weapon complex and the unprecedented non-proliferation challenges associated with the breakup of a nuclear weapon state. It describes the high-level diplomatic bargaining efforts to consolidate in Russia the nuclear weapons based in newly independent Belarus, Kazakhstan and Ukraine and to strengthen central control over these weapons. It surveys the problems associated with dismantling nuclear weapons and the difficulties involved in safely storing and disposing of large stockpiles of fissile material. It reviews the key provisions of the principal nuclear arms control measures and initiatives, including the START I and START II treaties. Finally, the authors assess the contribution of international assistance programmes to the denuclearization process under way in the former Soviet Union.

A dynamical system is called isochronous if it features in its phase space an open, fully-dimensional region where all its solutions are periodic in all its degrees of freedom with the same, fixed period. Recently a simple transformation has been introduced, applicable to quite a large class of dynamical systems, that yields autonomous systems which are isochronous. This justifies the notion that isochronous systems are not rare.In this book the procedure to manufacture isochronous systems is reviewed, and many examples of such systems are provided. Examples include many-body problems characterized by Newtonian equations of motion in spaces of one or more dimensions, Hamiltonian systems, and also nonlinear evolution equations (PDEs).The book shall be of interest to students and researchers working on dynamical systems, including integrable and nonintegrable models, with a finite or infinite number of degrees of freedom. It might be used as a basic textbook, or as backup material for an undergraduate or graduate course.

Since 1957, the Pugwash Conferences have brought together influential scholars and public figures concerned with reducing the danger of nuclear war. Meeting in private as individuals, rather than as representatives of their governments or institutions, Pugwash participants exchange views with a combination of candour and flexibility seldom found i

Reporting a novel breakthrough in the identification and investigation of solvable and integrable nonlinearly coupled evolution ordinary differential equations (ODEs) or partial differential equations (PDEs), this text includes practical examples throughout to illustrate the theoretical concepts. Beginning with systems of ODEs, including second-order ODEs of Newtonian type, it then discusses systems of PDEs, and systems evolving in discrete time. It reports a novel, differential algorithm which can be used to evaluate all the zeros of a generic polynomial of arbitrary degree: a remarkable development of a fundamental mathematical problem with a long history. The book will be of interest to applied mathematicians and mathematical physicists working in the area of integrable and solvable non-linear evolution equations; it can also be used as supplementary reading material for general applied mathematics or mathematical physics courses.
