A collaboration between Italian and Soviet academic institutions, this Workshop was centered on themes selected for future joint work, covering areas within and without conventional boundaries.

"Astronomy and Astrophysics Abstracts" appearing twice a year has become oneof the fundamental publications in the fields of astronomy, astrophysics andneighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. The abstracts are classified under more than a hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world.

The “Scientific Highlights in Memory of Léon Van Hove” meeting brought together many distinguished scientists and several top officials of the European Community in honor of Léon Van Hove, an outstanding European scientist who contributed immensely to the research and development of mathematical and theoretical physics. One of the most influential physicists of the post-war period, Léon Van Hove inspired new research and work from statistical mechanics to field theory and multiparticle production. The papers in this volume recollect Léon Van Hove's early days as a scientist and recount his efforts in favor of scientific collaboration across national and international boundaries and of the cultural integration of Europe. Such insight must surely interest those who seek beyond academic and research knowledge in physics to understand its history and development, seen through the life and work of Léon Van Hove.

This volume contains invited and contributed papers of eminent scientists who are deeply involved in the field of strongly correlated electron systems and high-Tc superconductivity. The topics of the papers include the Hubbard model, the t-J model, the polaronic model for high-Tc superconductivity, Fermi liquid and non-Fermi liquid theory, and heavy fermion systems.

Vols. for 1975- include publications cataloged by the Research Libraries of the New York Public Library with additional entries from the Library of Congress MARC tapes.
