Gyula KÅ‘nig

Julius King (Hungarian: Kőnig Gyula, born December 16, 1849 in Győr, † April 8, 1913 in Budapest) was a Hungarian mathematician.

Life

Julius King, both literary and mathematical- scientific gifted, studied in Vienna and 1868 in Heidelberg first medicine. After he had worked for Hermann von Helmholtz via electrical stimulation of nerves, he received his doctorate in 1870 at the Leo Konigsberg then a very popular with the mathematical subject of the theory of modular equations of elliptic functions. The dissertation consists of 24 pages. In Berlin deepened his mathematical studies at King Leopold Kronecker and Karl Weierstrass and then went as a teacher to Budapest. In 1874 he was appointed professor at the local Technical University, where he worked all his life - for three terms of office as dean and rector. In 1889 he became a member of the Hungarian Academy of Sciences. In 1905 he retired, but continued to hold lectures on his areas of interest. His son Dénes König also emerged as a mathematician.

Work

King worked on many mathematical areas. With his investigations of polynomial ideals, discriminants and elimination theory, he can be regarded as a link between Leopold Kronecker and David Hilbert and Emmy Noether.

King has remained mainly as a result of his contributions to Cantor's set theory in mind, among other things, by the set of king.

About King

Georg Cantor estimated King initially very high. In a letter to Philip Jourdain in 1905 he wrote:

Later Cantor revised his attitude towards King:
