The aim of this workshop was to take advantage of the recent freedom available to scientists in the Soviet Union (now Commonwealth of Independent States) to travel to the West in order to develop both contacts and an awareness of current research between research workers from East and West, most of whom have formerly had little contact. We consider this aim was achieved and are grateful for the substantial financial support from the European Office of the U.S. Office of Naval Research and the European Research Office of the U.S. Army. In addition we thank the home institutions or other fund providers which supported the travel costs of participants and the subsistence of western participants. The support of Bristol University's Department of Mathematics in holding the meeting is greatly appreciated.
