The theory of Quantum Groups is a rapidly developing area§with numerous applications in mathematics and theoretical§physics, e.g. in link and knot invariants in topology,§q-special functions, conformal field theory, quantum§integrable models. The aim of the Euler Institute's§workshops was to review and compile the progress achieved in§the different subfields. Near 100 participants came from 14§countries. More than 20 contributions written up for this§book contain new, unpublished material and half of them§include a survey of recent results in the field (deformation§theory, graded differential algebras, contraction technique,§knot invariants, q-special functions).§FROM THE CONTENTS: V.G.
