Geometry, if understood properly, is still the closest link between mathematics and theoretical physics, even for quantum concepts. In this collection of outstanding survey articles the concept of non-commutation geometry and the idea of quantum groups are discussed from various points of view. Furthermore the reader will find contributions to conformal field theory and to superalgebras and supermanifolds. The book addresses both physicists and mathematicians.
The book describes the close relationship between physics and geometry as it is understood nowadays. The reader will find inportant contributions to non-commutative geometry, quantum groups, conformal field theory, and integrable systems.
