The international Workshop on Classical and Quantum Integrable Systems will be held next year in Dubna on January 24 - 28, 2005. This Workshop continues the tradition of the all-Russia winter seminars initiated in the late 1980s by M.V.Saveliev which previously took place in Dubna and Protvino. The scientific scope of the Workshop covers advanced methods for studying integrable systems and their symmetry properties recent investigations of specific integrable models in classical and quantum mechanics, statistical models, and the theory of stochastic processes new results in all areas of contemporary mathematics related to the theory of integrable systems It is currently planned to bring together 50 - 70 active researches in these fields. Traditionally, we expect significant participation of scientists from the Institute for High Energy Physics (Protvino), Landau Institute of Theoretical Physics (Chernogolovka); Lebedev Physical Institute and Institute of Theoretical and Experimental Physics (Moscow); Steklov Mathematical Institute (Moscow and St.Petersburg branches). At the same time, we welcome scientists from around the world and we hope their participation will contribute considerably to the objectives of the Workshop. The Workshop will be organized as 6 -- 10 lectures of about 40 min. duration each day. Time for free scientific intercources will also be reserved. Due to necessity to complete visa formalities, the registration deadline for foreign participants is December 5. The conference fee is $ 250 which covers the roundtrip transportation from the airport to Dubna, the hotel accommodation and the banquet. The Organizing Commitee has a limited number of grants to cover living and in certain cases travel expences for participants from Russia. A decision on the distribution of funds will be taken at the end of December 2004. Russian participants are kindly asked to send their requests by this date. For participants from Germany and from East European countries their conference fee and in certain cases their travel expences can be (at least, partially) covered by grants of UNESCO - Regional Bureau for Science in Europe (ROSTE) and by the Heisenberg-Landau and Bogoliubov-Infeld Programs.
