This volume contains the proceedings of two international colloquia held in Japan in 1992. The various contributions by pre-eminent scientists cover the fields of quantum field theory, statistical and solid state physics, quantum groups and subfactors and index theory, and operator algebras and related topics. Together they present an authoritative overview of the latest developments by pioneers in these fields. Most of the contributions are self-contained. For graduate students and researchers in mathematics and mathematical physics.
