Symmetry Methods in Physics. In memory of Proffessor YA.A. Smorodinsky

Present Volumes contain the Proceeding of the International Workshop on Symmetry Meta ods in Physics, dedicated to the memory of Professor Yakov Smorodinsky, was held at Dubna Russia, on July 6-10, 1993.

The wide scope of the Workshop included dynamical symmetry and super-integrable sys tems, quantum algebras and groups, special functions and group representation theory, geo metric methods in quantum theory, quantum optics and coherent states, symmetry methods in nuclei, Lie symmetries and the few-body problem, as well as new applications.

The extraordinary scientific personality of Yakov Smorodinsky and his great contribution to symmetry concepts in physics with wide application are steering all diver the world. He has inspired a large number of pupils and influenced scientists working in different countries

These were the reasons why the idea of this Workshop has attracted the attention of scies tists from Bulgaria, Canada, the Czech Republic, England, France, Germany, Greece, Hungary, India, Israel, Italy, Japan, Mexico, Poland, Slovak Republic, Republic of South Africa, former Soviet Union, Spain and the USA.

The participants suggested that the Workshop should become traditional. This is important to unite scientists dealing with symmetry problems in different fields of physics. It will also express deep respect to the memory of Yakov Smorodinsky.

The International Advisory Committee and the Organizing Committee supported sugges tion of the participants to turn the Smorodinsky Symposium «Symmetry Methods in Physics into a regular event.

The Editors are grateful to Ms. T.L.Komolova for her help in preparing these Volumes for publication and to Mr. Yu. Tumanov for photographs.
