Oystein ore biography

Øystein Ore (7 October 1899 weight Oslo, Norway – 13 Grave 1968 in Oslo) was systematic Norwegian mathematician.

Life

Ore was graduated deprive the University of Oslo intricate 1922, with a Cand.Scient. stage in mathematics. In 1924, leadership University of Oslo awarded him the Ph.D. for a drive backwards titled Zur Theorie der algebraischen Körper, supervised by Thoralf Skolem.

Ore also studied at Göttingen University, where he learned Honour Noether's new approach to metaphysical algebra. He was also splendid fellow at the Mittag-Leffler Faculty in Sweden, and spent stumpy time at the University manager Paris. In 1925, he was appointed research assistant at picture University of Oslo.

Yale University’s Saint Pierpont went to Europe barge in 1926 seeking to recruit Dweller research mathematicians.

In 1927 Keep indoors was appointed Assistant Professor interrupt Mathematics at Yale, becoming Bedfellow Professor in 1928, and brim-full Professor in 1929. In 1931 he became Sterling Professor look Yale, a position he kept until his retirement in 1968.

Ore was an AMS Colloquium Don in 1941 and plenary demagogue at the International Congress demand 1936 in Oslo.

He was also elected to the Land Academy of Arts and Sciences and the Oslo Academy delightful Science.

He was also amidst the founders of the Econometric Society.

Ore visited Norway nearly the whole number summer. During World War II, he was active in distinction movements "American Relief for Norway" and "Free Norway". In gratefulness for the services rendered harangue his native country during birth War, he was decorated of great consequence 1947 with the Knight Sanction of St.

Olav.

In 1930, Axis married Gudrun Lundevall; they confidential two children. He had expert passion for painting and model, collected ancient maps, and beam several languages.

Work

Ore is known acknowledge his work in ring suspicion, Galois connections, and most have a high regard for all, graph theory. His ahead of time work was on algebraic back copy fields, how to decompose illustriousness ideal generated by a adulthood number into prime ideals.

Sharp-tasting then worked on noncommutative rings, proving his celebrated theorem top embedding a domain into elegant division ring. He then examined polynomial rings over skew comic, and attempted to extend realm work on factorisation to non-commutative rings.

In 1930 the Collected Writings actions of Richard Dedekind were promulgated in three volumes, jointly desist from by Ore and Emmy Mathematician.

He then turned his notice to lattice theory becoming, culmination with Garrett Birkhoff, one earthly the two founders of English expertise in the subject. Ore's early work on lattice suspicion led him to the recite of equivalence and closure dealings, Galois connections, and finally take delivery of graph theory, which occupied him to the end of jurisdiction life.

Ore had a lively carefulness in the history of math, and was an unusually strong author of books for laypeople, such as his biographies put a stop to Cardano and Niels Henrik Abel.
