Principle of Invariance and its Applications

International Symposium devoted to the 40^th anniversary of the Principle of Invariance Introduction to the Radiation Transfer Theory
October 26-30, 1981, Byurakan, Armenia

The symposium was devoted to the 40th anniversary of V.A. Ambartsumian’s principle of invariance introduction to the radiation transfer theory. Results of the application of principle of invariance and its development in various fields of modern science were discussed.

Astrophysicists, physicists, mathematicians – representatives of different schools of exact sciences participated in the symposium, confirming the community of importance of the transfer theory for these sciences.

There were some prominent scientists among the participants, as S. Chandrasekhar (USA), C.H. Papas (USA), V.V. Sobolev (USSR). Altogether there were 65 participants, including 8 from the Byurakan Observatory, 12 from other institutes of Armenia, 35 from other republics of the Soviet Union, and 10 scientists from 7 foreign countries (USA, Japan, France, Czechoslovakia, Hungary, GDR, and Poland). 46 talks were presented, including 3 invited reviews (by V.A. Ambartsumian, S. Chandrasekhar and V.V. Sobolev), 23 reports on radiation transfer theory and 20 reports on applications to other problems of physics and mathematics. Byurakan astronomers had 8 talks.
