Over the last two decades, topological ideas have found increasingly more applications in quantum field theory. Topological field theories are the culmination of these developments, and they formed the dominating theme of the conference. The other focal point was two-dimensional quantum gravity. The participation of such leading mathematicians as M Atiyah, R Bott, G Segal, and I Singer, is a testmony to the deep interplay of mathematics and theoretical physics.

The Salamfest was held to honor Prof Abdus Salam whose scientific contribution to the development and dissemination of physics has deeply influenced the course of scientific advancement. Colleagues, collaborators and former students met together to celebrate his scientific achievements, and discuss the highlights of recent advances in experiment and phenomenology in particle and condensed matter physics.The Contributors are: A Ali, G Altarelli, L Alvarez-Gaumé, D Amati, J Bahcall, A Chamseddine, R Delbourgo, M Duff, J Ellis, J Feltesse, P Frampton, M Green, G 't Hooft, T Kibble, G Mack, Y Ne'eman, L O'Raifeartaigh, J Pati, R Peccei, S Randjbar-Daemi, Riazuddin & Fayyazuddin, D Schramm, H Schröder, D Sciama, E Sezgin, Q Shafi, C Vafa, S Weinberg, P West, B Winstein, E Witten, C N Yang, A Zichichi and B Zumino.

This School presented topics of current interest in high energy physics including Superstrings, Unified Theories and Cosmology.

This volume presents papers that reflect recent research in string theory and quantum gravity.

Presents essays on recent developments in high energy physics and cosmology.

Topics covered in this study of high energy physics and cosmology include neutrino physics; W algebras, W gravities and their modular spaces; the nonlinear Schrodinger hierarchy in matrix models, and the ground ring of W3 string.

This volume reports on work done on string theory and quantum gravity at the ICTP School and Workshop. Topics covered include quantum aspects of Black Holes; the dark side of string theory - Black Holes and Black Strings; and some recent developments in closed string field theory.

The aim of this interdisciplinary conference was to bring together experts in quantum field theory and condensed matter physics to survey the latest exciting developments in this border-line field, such as the Chern-Simons field theory and quantum hall effect, anyon superconductivity, Yang-Baxter equations and quantum groups, conformal field theory and multi-channel kondo effect, matrix models and quantum gravity, etc.This set of proceedings contains brief reviews contributed by leading experts in the field.

This volume is a collection of papers presented at the Summer School, ICTP, 14 June - 30 July. Topics covered include: comparing the elementary quark versus the preonic approach to unification, quark matter and nuclear collisions and effective actions and topological string amplitudes.

Topics covered include: exact results for two-dimensional N=2 supersymmetric theories; a string project in multicolour QCD; matrix models and string theory; black hole evaporation and quantum gravity; gauge theory and lattice strings; and quantization of mirror symmetry.

These proceedings of the 1994 Summer School ICTP, held at Trieste, Italy, from 13 June - 29 July 1994, should be of interest to high energy physicists and cosmologists.

The collected articles in this text are the proceedings of a conference on high energy physics and cosmology. Topics covered include new results in topological field theory and abelian guage theory, and observation of top quark at CDF.

The proceedings of the Annual Trieste Summer School on High Energy Physics and Cosmology covers many of the leading research areas in these fields. They are valuable resources for active researchers, including advanced graduate students as well as postdoctoral fellows.

In this volume recent developments in the nonperturbative aspects of string theory, duality in N = 1 string compactifications, orientifolds and F-theory as well as the matrix model description of M-theory are reported. The D-brane approach to black holes and their entropy is also discussed.The phenomenological part is devoted to the main fields of present-day astroparticle physics: supersymmetry, neutrino physics and cosmology. The two most important aspects of supersymmetry are covered: Searches for superpartners (G Kane) and mechanisms of supersymmetry breaking (G Dvali).Results from recent neutrino experiments and their implications are presented (S Pakvasa). The central issues of modern cosmology such as inflation (R Brandenberger), formation of topological defects (T Vachaspati) and dark matter (M Kamionkowski) are discussed.

These proceedings form an analysis of the nonperturbative aspects of strings, branes and supersymmetry. Issues addressed include supermembranes and the Matrix theory; non-supersymmetric strings; superembeddings; aspects of the M5-brane; and domain walls and the universe.

A volume of proceedings from the 1999 Spring Workshop on Superstrings and Related Matters, held in Trieste, Italy. Subjects covered include: large N gauge theories and ADS/CFT correspondence; black holes physics; duality and instantons in string theory; D-branes and F-theory; and more.
