Vojtěch Jarník
Vojtěch Jarník (born December 22, 1897 in Prague , † September 22, 1970 ibid) was a Czechoslovak mathematician . He mainly dealt with number theory , but also with analysis .
Life
Jarník studied from 1915 at the Charles University in Prague , worked there as an assistant after graduating and from 1919 to 1921 lecturer at the Technical University of Brno . He completed his doctoral thesis O kořenech funkcí Besselových (On the Roots of Bessel Functions) in 1921. Before he became professor of mathematics at the Charles University in Prague in 1928, he worked for 3 semesters from autumn 1923 (and again in 1927/28) under the direction of Edmund Landau in Göttingen . Jarník held his chair in Prague until his retirement in 1968.
Together with Landau he examined the question of how many points with integer coordinates (grid points) are contained in a given closed area (generalizations of the Gaussian circle problem ), which later remained one of his main areas of work. He also discovered Prim's algorithm for minimal spanning trees .
Jarník was the author of around 90 mathematical articles, a widely used multi-volume textbook on analysis, and co-editor of the journal Acta Arithmetica .
The Vojtěch Jarník Competition is a competition for mathematics students that is held regularly in the Czech Republic.
The asteroid (4023) Jarník is named after him.
Břetislav Novák was one of Jarník's doctoral students .
