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

Live and act

József Kürschák studied at the Budapest Technical University from 1881 to 1886 and became a teacher of mathematics and physics. For two years he taught in a place in Slovakia. Then he went back to the Technical University, where he received his doctorate in 1890 and was a member of the faculty from 1891. In 1900 he became a professor there. He was one of the founders of the special, problem-oriented style of teaching in Hungary, which emphasized competition among students and pupils.

At the International Congress of Mathematicians in Cambridge in 1912, he founded the evaluation theory of the body with his lecture (and his essay in the Journal for Pure and Applied Mathematics in 1913) , with the word “evaluation” also being introduced by Kürschák. In this, Kürschák proved that every evaluated field has an extension that is algebraically closed and complete. His motivation came from Kurt Hensel and his -adic numbers , which Kürschák wanted to put on a secure basis.

In 1898 he gave a purely geometrical proof that the area of ​​a dodecahedron inscribed in a unit sphere 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 König .

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