In 1934, she earned a Ph. D. in mathematics from Yale under the direction of Øystein Ore .< ref > Though some books, including Kurt Beyer's Grace Hopper and the Invention of the Information Age, reported that Hopper was the first woman to earn a Yale PhD in mathematics, the first of ten women prior to 1934 was Charlotte Cynthia Barnum ( 1860-1934 ).

Work on the subject was minimal until the early 1930s, when Garrett Birkhoff and Øystein Ore began publishing on universal algebras.

The term groupoid is an older, but still commonly used alternative which was introduced by Øystein Ore.

The best vertex degree characterization of Hamiltonian graphs was provided in 1972 by the Bondy – Chvátal theorem, which generalizes earlier results by G. A. Dirac ( 1952 ) and Øystein Ore.

Over the course of his entire career, he had but one Ph. D. student, but that student was a productive one, Øystein Ore, who went on to a career in the USA.

In mathematics, a harmonic divisor number, or Ore number ( named after Øystein Ore who defined it in 1948 ), is a positive integer whose divisors have a harmonic mean that is an integer.

The term quasinormal subgroup was introduced by Øystein Ore in 1937.

Ore had a lively interest in the history of mathematics, and was an unusually able author of books for laypeople, such as his biographies of Cardano and Niels Henrik Abel.

Roads from the Old Town valley lead towards the Victorian area of Clive Vale and the former village of Ore, from which " The Ridge ", marking the effective boundary of Hastings, extends north-westwards towards Battle.

The final SSSI, Hastings Cliffs to Pett Beach, is within the Ore ward of Hastings, extending into the neighbouring Fairlight and Pett parishes.

Some of the areas and suburbs of Hastings are Ore Valley, St Leonards, Silverhill, West St Leonards, and Hollington.

Ore, Silverhill and Hollington were once villages that have since become part of the Hastings conurbation area during rapid growth.

Mormugao Port and Panambur ( New Mangalore Port ) handle most of the Iron Ore export from India especially to Japan.

Ore is located by prospecting techniques, followed by the exploration and examination of deposits.

Ore bodies often contain more than one valuable metal.

Ore, for processing, and waste rock, for disposal, are brought to the surface through the tunnels and shafts.

Ore mills generate large amounts of waste, called tailings.

The most famous nutcracker carvings come from Sonneberg in Thuringia ( also a center of dollmaking ) and from the Ore Mountains.

Ore bodies are formed by a variety of geological processes.

Ore deposits are classified according to various criteria developed via the study of economic geology, or ore genesis.

Ore deposits of palladium and other PGMs are rare, and the most extensive deposits have been found in the norite belt of the Bushveld Igneous Complex covering the Transvaal Basin in South Africa, the Stillwater Complex in Montana, United States, the Thunder Bay District of Ontario, Canada, and the Norilsk Complex in Russia.

The Erzgebirgskreis district covers the Ore Mountains, and the Schweiz-Osterzgebirge district includes Saxon Switzerland and the Eastern Ore Mountains.

Dresden's founding and early growth is associated with the eastward expansion of Germanic peoples, mining in the nearby Ore Mountains, and the establishment of the Margraviate of Meissen.

Dresden lies on both banks of the river Elbe, mostly in the Dresden Basin, with the further reaches of the eastern Ore Mountains to the south, the steep slope of the Lusatian granitic crust to the north, and the Elbe Sandstone Mountains to the east at an altitude of about.

Because of its location on the banks of the Elbe, into which some water sources from the Ore Mountains flow, flood protection is important.

During 1992 and 1993, Burzum recorded four albums ; however, in 1994 Vikernes was convicted and imprisoned for the murder of guitarist Øystein " Euronymous " Aarseth and the arson of three churches.

Sigurd Jorsalfare, Øystein Magnusson and Olaf Magnusson succeed him as joint kings of Norway.

According to an interview in Blood & Honour magazine, he got in touch with neo-Nazi organisation Zorn 88 ’ s ( later called Norges Nasjonalsocialistiske Bevegelse ) magazine Gjallarhorn in 1992 and joined White Aryan Resistance before he murdered Øystein Aarseth.

The Holmenkollen Chapel was destroyed by arson in 1992 by black metal artists Varg Vikernes, Bård “ Faust ” Eithun and Øystein “ Euronymous ” Aarseth, but later rebuilt.

Øystein Djupedal was elected Minister of Education and Research, and held that position for two years.

Borknagar is a progressive black metal band from Bergen, Norway, founded in 1995 by Øystein Garnes Brun.

Borknagar was founded by a remaining member of the Norwegian death metal band Molested when then-member Øystein Brun became tired of the brutal aspects of the band's music.

Øystein formed Borknagar to explore a more melodic outlet of expression, inspired by the burgeoning black metal movement Norway was experiencing and looking to push the boundaries of what was considered " traditional " black metal music.

Borknagar released a lighter album, Origin, which is " an acoustic effort based entirely on the epic and progressive aspect of the band ", according to Øystein G. Brun's statement on blabbermouth. net.

In March 2008, Asgeir posted an announcement from Øystein on UltimateMetal forums stating that Erik Tiwaz and Jens F. Ryland had again become official members of the band, and that the band were aiming for a January 2009 release.
