Otto Varga

* Szepetnek, November 22, 1909 – † Budapest, June 14, 1969 / mathematician, university professor, member of the Hungarian Academy of Sciences (1965) ; ; He was born in Szepetnek, Zala County, but moved with his family to Poprad at a young age and completed high school in Késmárk. He studied at the Vienna University of Technology and then at the Charles University in Prague, where he obtained a teaching certificate in mathematical representational geometry in 1933 and a doctorate in 1934. He was a scholarship holder in Hamburg from 1933 to 1935. He taught at the University of Prague from 1935 to 1939, then after the German occupation he went to Kolozsvár, where he became a private teacher of the subject “algebra and the application of analysis to geometry” at the Franz Joseph University. During the II. After World War II, he settled in Debrecen, where he taught as a university professor from 1948. The Hungarian Academy of Sciences elected him a corresponding member in 1950 and a full member in 1965. Between 1958 and 1967, he was a head of department at the Department of Mathematics of the University of Civil Engineering and Transport (ÉKME). In 1967, he joined the Institute of Mathematical Research of the Hungarian Academy of Sciences, where he headed the differential geometry group as a senior research fellow. In 1949, he founded the international journal Publicationes Mathematicae together with Alfréd Rényi (1921–1970) and Tibor Szele (1918–1955). In 1944, he won the Gyula Kőnig Prize and in 1952, he received the Kossuth Prize. His main research area is differential geometry. He has published 57 papers in domestic and foreign journals. He is credited with the new derivation and detailed explanation of Cartan's foundation of Finsler geometry. His results in Blaschke's integral geometry are significant. He applied these to Finsler geometry and geometric optics. He presented his research in differential geometry at several international congresses. ; ; His main works: ; Integralgeometrie, 1936, ; Beiträge zur Theorie der Finslerschen Räume und der affinzusammenhängenden Räume von Linienelementen, 1936, ; Az invariant differential ättningra a Finsler-féle terebekb (Mathematical and Physical Papers), 1941, ; Az integralgeometrya a geometriai optikab (MTA III. Oszt. Közl.), 1951, ; Geometric characterization of Finsler spaces with scalar curvature and constant curvature (academic chair holder), 1951, ; The moving n-edge method and its applications in Finsler geometry (academic chair holder), 1966.
