Felix Frankl

from Wikipedia, the free encyclopedia

Felix Issidorowitsch Frankl ( Russian Феликс Исидорович Франкль ; born March 12, 1905 in Vienna , † April 7, 1961 in Nalschik ) was an Austrian - Soviet mathematician , physicist and university professor .

Life

Frankl came from a wealthy Jewish family. His father owned a small factory near Vienna. He inherited communist beliefs from his parents . He studied at the mathematics faculty of the University of Vienna under Hans Hahn and graduated in 1927 as Dr. phil.

Frankl was already active in the labor movement during his studies . In 1928 he joined the Communist Party of Austria . In September 1928 he took part in the 8th International Congress of Mathematicians in Bologna . There he met the Soviet topologist Pavel Sergejewitsch Alexandrow know. When Alexandrov visited him in Vienna, he asked Alexandrov to help him move to Moscow . Alexandrow forwarded the request to Otto Juljewitsch Schmidt in the People's Commissariat for Education of the RSFSR , who initially said that they had enough communists of their own and that Frankl should prepare the revolution in Austria. Nevertheless, Schmidt helped so that Frankl emigrated to Moscow in 1929 . He now worked as a research assistant in the Communist Academy at the Central Executive Committee of the USSR . He was a member of the local society of Marxist mathematicians. He has published work on dimension theory in German and Austrian journals. However, he was dissatisfied that the mathematical milieu in Moscow was not ideologized.

In 1931 Frankl moved to the Moscow Central Aerohydrodynamic Institute (ZAGI) as a research assistant in the physical- mathematical department, of which he then became scientific director. In 1932 he became a member of the CPSU . In 1933 he gave a systematic and fundamental lecture on gas dynamics . His work there focused on aerodynamics at supersonic speeds and the theory of compressible boundary layers . In 1934 he received his doctorate in technical sciences . With Mstislav Vsevolodowitsch Keldysch he published a strict justification of Nikolai Yegorowitsch Zhukovsky's screw theory . Khalil Achmedowitsch Rachmatulin completed his at Frankl postgraduate . In 1935 Frankl took part in the First International Topology Conference in Moscow. In 1936 he received his doctorate in physical and mathematical sciences . Under Frankl and Lev Gerassimowitsch Loitsjanski's leadership, a Soviet center for theoretical and experimental gas dynamics research was established at ZAGI. Frankl's book on the fundamentals of gas dynamics was greatly appreciated by Grigori Isaakowitsch Barenblatt and Oleg Sergejewitsch Ryschow .

1944 Frankl was head of the Department for missile weapons in the Dzerzhinsky - Artillery Academy. Despite the isolation of the work there, Frankl continued to publish. In 1946 he became a corresponding member of the Academy of Artillery Sciences founded in 1946 (now the Academy of Rocket and Artillery Sciences).

In 1950 Frankl was expelled from the CPSU because of a critical remark about Stalin in the seminar and banished to Frunze . There he headed the Chair of Theoretical Physics of the Kyrgyz State Pedagogical Institute, which in 1951 became the Kyrgyz State University. Like all exiles, Frankl had to introduce himself to the special headquarters every day. After the XX. In 1956, Frankl was rehabilitated and re-admitted to the CPSU. In 1956 he became a member of the National Commission of the USSR for Theoretical and Applied Mechanics, founded in 1956 . In 1957 he received the Leonhard Euler Gold Medal from the Academy of Sciences of the USSR .

When the Pedagogical Institute in Nalschik became the Kabardino-Balkarian State University in 1957 , Frankl took over the management of the chair for theoretical physics. In 1958 Frankl's translation of the third volume of the Institutiones calculi integralis by Leonhard Euler appeared . In addition to French , Latin and Russian , Frankl also mastered Kyrgyz and Kabardian . In Nalchik he continued to deal with problems of gas dynamics and extended the long list of his publications. In 1961 he presented a generalization of the Tricomi problem with application to the theory of the Laval nozzle .

Books from Frankl's personal library were given to the library of the Kabardino-Balkarian State University.
