Papers of russian and foreign authors aminly on the subject typical for the series "Problems of Quantum Field Theory and Statistical Physics", are presented in this volume. The first ten papers of the volume are written by the participants of the 2-nd International Workshop on Quantum Groups and Integrable Systems (PDMI-Florence) which took place at the St.Petersburg Department of V.A.Steklov Mathematical Institute of Russian Academy of Sciences in the end of May, 1997.
