The publication of the first edition of “Introduction to Supersymmetry and Supergravity” was a remarkable success. This second edition contains a substantial amount of new material especially on two-dimensional supersymmetry algebras, their irreducible representations as well as rigid and local (i.e. supergravity) theories of 2-dimensional supersymmetry both in x-space and superspace. These theories include the actions for the superstring and the heterotic string. In addition, a chapter is devoted to a discussion on superconformal algebras in two dimensions and contains an account of super operator product expansion.

Supersymmetry, supergravity and superstring are the most popular research topics in particle physics. In particular, the phenomenological studies beyond the standard model have become very popular in view of possible identification or exclusion of supersymmetric particles in the future. Also, the lightest supersymmetric particle in most supersymmetric models can be a good candidate for dark matter in the universe.The recent developments in supersymmetry with important applications to particle physics are the main theme of this book, which includes superstring calculations with D-branes, TeV-scale gravity, superstring- and supergravity-inspired interactions, supersymmetric GUT, supergravity phenomenology, and cosmological implications of LSP.

The continuation of global poverty is inextricably entwined with the fundamental philosophy of the market economy. It is driven by the individual's neverending desire for “profit”, leading to a critically imbalanced distribution of resources. As an entrepreneurial initiative, this book advocates a shift in the responsibility for relief of poverty away from the government to the private sector, and in particular to corporate entities. The concept of the “residual” is used as the cornerstone of business operations and wealth distribution. Corporate decision-makers, while making proprietary decisions for resources allocation, must assume stewardship responsibility and be accountable not just to financial investors but to all contributors of the corporate entity.

The twenty-fifth anniversary edition featuring a new Preface, invaluable for graduate students and researchers in high energy physics and astrophysics.

Recent devopments, particularly in high-energy physics, have projected group theory and symmetry consideration into a central position in theoretical physics. These developments have taken physicists increasingly deeper into the fascinating world of pure mathematics. This work presents important mathematical developments of the last fifteen years in a form that is easy to comprehend and appreciate.

The Super Field Theory Workshop, held at Simon Fraser University, Vancouver, Canada July 25 - August 5, 1986 was originally intended to be a sequel to the 1983 Chalk River Workshop on Kaluza-Klein Theories and the 1985 Workshop on Quantum Field Theories held at the University of Western Ontario. The scope of the workshop was therefore not to be very big, with a program of about 20 papers, an anticipated 30 to 45 participants, and with much time scheduled for discussion and personal contact. These goals were soon changed in the face of wide interest in the workshop, both for participation and for giving talks, so that the workshop materialized with about 90 participants and 40 talks. This volume contains the texts, some considerably expanded from the oral version, of most of the talks pre sented at the workshop. Not included are a few talks whose manuscripts were not made available to the editors. In the last few years the subject of particle physics and unified field theory has developed in a way not witnessed in the last fifty years: a confluence with mathematics, especially in geometry, topology and algebra at an advanced level. This has vastly expanded the horizon of the disci pline and heightened the expectation that a true understanding of the fun damental laws of physics may soon be within reach. Most aspects of this new development are covered, many in pedagogical detail, by articles in this volume.
