Jovan Karamata
Jovan Karamata ( Serbian - Cyrillic Јован Карамата ; born February 1, 1902 in Zagreb , † August 14, 1967 in Geneva ) was a Yugoslav mathematician who made contributions to analysis , especially the theory of slowly varying functions.
Life
Karamata first grew up in Zemun . When the First World War broke out in 1914, his father sent him and his siblings to Switzerland, where he attended a mathematics and science high school in Lausanne . From 1920 to 1922 he studied at the technical faculty of the University of Belgrade , then switched to the mathematics department of the philosophical faculty and graduated in 1925. Three months later he submitted his doctoral thesis, in 1926 he received his doctorate under Mihailo Petrović ( O jednoj vrsti granica sličnih određenim integralima ). He spent the years 1927 and 1928 in Paris on a Rockefeller scholarship, after which he became an assistant for mathematics at the University of Belgrade. In 1930 he became a lecturer there, in 1937 an associate professor and in 1950 a full professor, in 1951 he was appointed to the University of Geneva , where he remained until his death.
In 1930 Karamata showed that a positive continuous function on the positive real numbers is then slowly varying, i.e. the condition for all
- For
met when for one for in shape
- with and for
can be written.
His PhD students included Vojislav Avakumović, Slobodan Aljančić, Ranko Bojanic, and Ronald Coifman .
