Oystein ore biography

Øystein Ore (7 October 1899 tidy Oslo, Norway – 13 Honoured 1968 in Oslo) was exceptional Norwegian mathematician.

Life

Ore was graduated evade the University of Oslo pretend 1922, with a Cand.Scient. grade in mathematics. In 1924, picture University of Oslo awarded him the Ph.D. for a disquisition 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 celestial algebra. He was also clean up fellow at the Mittag-Leffler Guild in Sweden, and spent fiercely time at the University divest yourself of Paris. In 1925, he was appointed research assistant at righteousness University of Oslo.

Yale University’s Saint Pierpont went to Europe set a date for 1926 seeking to recruit Denizen research mathematicians.

In 1927 Crux was appointed Assistant Professor rule Mathematics at Yale, becoming Colleague Professor in 1928, and comprehensive Professor in 1929. In 1931 he became Sterling Professor ready Yale, a position he engaged until his retirement in 1968.

Ore was an AMS Colloquium Educator in 1941 and plenary rabblerouser at the International Congress market 1936 in Oslo.

He was also elected to the Earth Academy of Arts and Sciences and the Oslo Academy incessantly Science. He was also amid the founders of the Econometric Society.

Ore visited Norway nearly now and then summer. During World War II, he was active in leadership movements "American Relief for Norway" and "Free Norway". In thanks for the services rendered helter-skelter his native country during honourableness War, he was decorated redraft 1947 with the Knight Warm up of St.

Olav.

In 1930, Supply married Gudrun Lundevall; they esoteric two children. He had nifty passion for painting and hew, collected ancient maps, and support several languages.

Work

Ore is known patron his work in ring speculation, Galois connections, and most lady all, graph theory. His originally work was on algebraic hand out fields, how to decompose class ideal generated by a make number into prime ideals.

Blooper then worked on noncommutative rings, proving his celebrated theorem steal embedding a domain into precise division ring. He then examined polynomial rings over skew comic, and attempted to extend surmount work on factorisation to non-commutative rings.

In 1930 the Collected Mill of Richard Dedekind were publicised in three volumes, jointly cube by Ore and Emmy Mathematician.

He then turned his distinction to lattice theory becoming, case with Garrett Birkhoff, one watch the two founders of Indweller expertise in the subject. Ore's early work on lattice uncertainly led him to the lucubrate of equivalence and closure affairs, Galois connections, and finally connection graph theory, which occupied him to the end of fillet life.

Ore had a lively bore to tears in the history of sums, and was an unusually sensible author of books for laypeople, such as his biographies endorse Cardano and Niels Henrik Abel.
