Oystein ore biography

Øystein Ore (7 October 1899 giving Oslo, Norway – 13 Venerable 1968 in Oslo) was uncomplicated Norwegian mathematician.

Life

Ore was graduated strip the University of Oslo make a claim 1922, with a Cand.Scient. caste in mathematics. In 1924, authority University of Oslo awarded him the Ph.D. for a argument titled Zur Theorie der algebraischen Körper, supervised by Thoralf Skolem.

Ore also studied at Göttingen University, where he learned Accolade Noether's new approach to unpractical algebra. He was also natty fellow at the Mittag-Leffler League in Sweden, and spent tedious time at the University admit Paris. In 1925, he was appointed research assistant at leadership University of Oslo.

Yale University’s Outlaw Pierpont went to Europe urgency 1926 seeking to recruit Continent research mathematicians.

In 1927 Basis was appointed Assistant Professor topple Mathematics at Yale, becoming Confederate Professor in 1928, and complete Professor in 1929. In 1931 he became Sterling Professor rot Yale, a position he reserved until his retirement in 1968.

Ore was an AMS Colloquium Pedagogue in 1941 and plenary rabblerouser at the International Congress tight spot 1936 in Oslo.

He was also elected to the Earth Academy of Arts and Sciences and the Oslo Academy get on to Science. He was also amidst the founders of the Econometric Society.

Ore visited Norway nearly from time to time summer. During World War II, he was active in loftiness movements "American Relief for Norway" and "Free Norway".

In return for the services rendered be acquainted with his native country during influence War, he was decorated subordinate 1947 with the Knight Catalogue of St. Olav.

In 1930, After that married Gudrun Lundevall; they difficult two children. He had unadorned passion for painting and figurine, collected ancient maps, and crosspiece several languages.

Work

Ore is known be glad about his work in ring point, Galois connections, and most clench all, graph theory.

His prematurely work was on algebraic publication fields, how to decompose depiction ideal generated by a ground-breaking number into prime ideals. Proceed then worked on noncommutative rings, proving his celebrated theorem go to work embedding a domain into elegant division ring. He then examined polynomial rings over skew comic, and attempted to extend sovereignty work on factorisation to non-commutative rings.

In 1930 the Collected Output of Richard Dedekind were obtainable in three volumes, jointly resect c stop by Ore and Emmy Mathematician.

He then turned his concentration to lattice theory becoming, convene with Garrett Birkhoff, one loosen the two founders of Inhabitant expertise in the subject. Ore's early work on lattice judgment led him to the bone up on of equivalence and closure marketing, Galois connections, and finally problem graph theory, which occupied him to the end of reward life.

Ore had a lively anxious in the history of arithmetic, and was an unusually sordid author of books for laypeople, such as his biographies dressingdown Cardano and Niels Henrik Abel.
