The Abdus Salam Memorial Meeting was held from the 19th to the 22nd of November, 1997 on the first anniversary of the death of Prof Abdus Salam, Nobel laureate and Founder-Director of the International Centre for Theoretical Physics. It was an opportunity for many of his colleagues and students to pay homage to him.

This invaluable volume, comprising the papers presented at the meeting, reflects the long-lasting passion of Prof Salam for the theory of the fundamental forces. Most of the contributions are concerned with recent developments in the theory of superstrings, including duality, D-branes and related topics.

This book contains a detailed and self-contained presentation of the replica theory of infinite range spin glasses. The authors also explain recent theoretical developments, paying particular attention to new applications in the study of optimization theory and neural networks. About two-thirds of the book are a collection of the most interesting and pedagogical articles on the subject.

This important book contains selected research papers of Prof Bunji Sakita. Included are his pioneering papers on SU(6) symmetry, strong coupling theory, string theory, supersymmetry and the method of collective coordinates. There is also a vivid personal account of his journey in physics. The book brings to light some of the key concepts of modern high energy physics.
