The ICTP has been holding a Summer Workshop in High Energy Physics and Cosmology since 1981. The primary goal of these workshops is to bring together active physicists from around the world, and to provide a platform where the frontier developments in the field are presented by leading workers. The atmosphere for the workshop was active and stimulating and each area was represented by leading physicists in the field.

Observations of neutrinos being emitted by the supernova SN1987A, star neutrinos, and atmospheric neutrinos have provided new insights into astronomy, as well as new unresolved phenomena such as the solar neutrino problem, spurring investigative studies among particle physicists and astrophysicists. One of the most important features of this book is its enumeration of a number of basic properties of neutrinos and their relationship to Grand Unified Theories, focusing on the origin of the neutrino's mass and the generation mixing of neutrinos. All the kamiokande results, detector performances, and complete references are included.
