József Kürschák

József Kürschák ( born March 14, 1864 in Budapest, † March 26, 1933 ) was a Hungarian mathematician.

Life and work

József Kürschák studied from 1881 to 1886 at the Technical University of Budapest and became a teacher of mathematics and physics. He taught for two years in a place in Slovakia. Then he went to the Technical University, where he received his doctorate in 1890 and 1891 belonged to the faculty. In 1900 he became a professor. He was one of the founders of the special, oriented to problems and laying on competition among students and pupils value the Hungarian teaching styles.

He founded in 1912 at the International Congress of Mathematicians in Cambridge with his lecture ( and his article in the Journal of Pure and Applied Mathematics 1913) the valuation theory, the body, with the word " review" was introduced by Kürschák. Kürschák proved that each evaluated body has an extension that is algebraically closed and complete. His motivation came from Kurt Hensel and his - adic numbers, which wanted to make Kürschák on a secured basis.

In 1898 he was a purely geometrical proof that the area of an inscribed in a unit sphere the dodecahedron is equal to three. Kürschák also examined the partial differential equations of the calculus of variations.

His students include John von Neumann, Rózsa Péter and Dénes king.

In 1897 he was inducted into the Hungarian Academy of Sciences.
