Tudor Ganea
Tudor Ganea (October 17, 1922 –August 1971) was a Romanian-American mathematician, known for his work in algebraic topology, especially homotopy theory. Ganea left Communist Romania to settle in the United States in the early 1960s. He taught at the University of Washington. Life and work He studied mathematics at the University of Bucharest, and then started his research as a member of Simion Stoilow's seminar on complex functions. His papers from 1949–1952 were on covering spaces, topological groups, symmetric products, and the Lusternik–Schnirelmann category. During this time, he earned his candidate thesis in topology under the direction of Stoilow. In 1957, Ganea published in the ''Annals of Mathematics'' a short, yet influential paper with Samuel Eilenberg, in which the Eilenberg–Ganea theorem was proved and the celebrated Eilenberg–Ganea conjecture was formulated. The conjecture is still open. By 1958, Ganea and his mentee, Israel Bernstein, were the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of Romania
The Kingdom of Romania ( ro, Regatul României) was a constitutional monarchy that existed in Romania from 13 March ( O.S.) / 25 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I of Romania and the Romanian parliament's proclamation of the Romanian People's Republic. From 1859 to 1877, Romania evolved from a personal union of two vassal principalities (Moldavia and Wallachia) under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), when it also received Northern Dobruja in exchange for the southern part of Bessarabia. The kingdom's territory during the reign of King Carol I, between 13 ( O.S.) / 25 March 1881 and 27 September ( O.S.) / 10 October 1914 is sometimes referred ...

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame". History Felix Klein and Georg Cantor are credited with putting forward the idea of an international congress of mathematicians in the 1890s.A.

Her first husband was Marin Preda, to whom she was married between 1955 and 1959 (or 1960). She encouraged him to publish the novel ''Moromeții'', whose manuscript she had found in a drawer. Her fiancé in the mid-1960s, mathematician Tudor Ganea, did not succeed in g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Lafayette, Indiana
West Lafayette () is a city in Wabash Township, Tippecanoe County, Indiana, United States, about northwest of the state capital of Indianapolis and southeast of Chicago. West Lafayette is directly across the Wabash River from its sister city, Lafayette. As of the 2020 census, its population was 44,595. It is the most densely populated city in Indiana and is home to Purdue University. History Augustus Wylie laid out a town in 1836 in the Wabash River floodplain south of the present Levee. Due to regular flooding of the site, Wylie's town was never built. The present city was formed in 1888 by the merger of the adjacent suburban towns of Chauncey, Oakwood, and Kingston, located on a bluff across the Wabash River from Lafayette, Indiana. The three towns had been small suburban villages which were directly adjacent to one another. Kingston was laid out in 1855 by Jesse B. Lutz. Chauncey was platted in 1860 by the Chauncey family of Philadelphia, wealthy land speculators. Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
