Caucher Birkar
Caucher Birkar ( ku, کۆچەر بیرکار, lit=migrant mathematician, translit=Koçer Bîrkar; born Fereydoun Derakhshani ( fa, فریدون درخشانی); July 1978) is an Iranian Kurdish mathematician and a professor at Tsinghua University and University of Cambridge. Birkar is an important contributor to modern birational geometry. In 2010 he received the Leverhulme Prize in mathematics and statistics for his contributions to algebraic geometry, and in 2016, shared the AMS Moore Prize for the article "Existence of minimal models for varieties of log general type". He was awarded the Fields Medal in 2018, "for his proof of boundedness of Fano varieties and contributions to the minimal model program". In his office at the University, Birkar has two photographs of Alexander Grothendieck, his favorite mathematician, who like Birkar, was a refugee and Fields medalist. Early life and education Birkar is a Kurd, born in 1978 in Marivan County, Kurdistan province, Iran, on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birational Geometry
In mathematics, birational geometry is a field of algebraic geometry in which the goal is to determine when two algebraic varieties are isomorphic outside lower-dimensional subsets. This amounts to studying mappings that are given by rational functions rather than polynomials; the map may fail to be defined where the rational functions have poles. Birational maps Rational maps A rational map from one variety (understood to be irreducible) X to another variety Y, written as a dashed arrow , is defined as a morphism from a nonempty open subset U \subset X to Y. By definition of the Zariski topology used in algebraic geometry, a nonempty open subset U is always dense in X, in fact the complement of a lower-dimensional subset. Concretely, a rational map can be written in coordinates using rational functions. Birational maps A birational map from ''X'' to ''Y'' is a rational map such that there is a rational map inverse to ''f''. A birational map induces an isomorphism from a ...

Kurds
ug:كۇردلار Kurds ( ku, کورد ,Kurd, italic=yes, rtl=yes) or Kurdish people are an Iranian ethnic group native to the mountainous region of Kurdistan in Western Asia, which spans southeastern Turkey, northwestern Iran, northern Iraq, and northern Syria. There are exclaves of Kurds in Central Anatolia, Khorasan, and the Caucasus, as well as significant Kurdish diaspora communities in the cities of western Turkey (in particular Istanbul) and Western Europe (primarily in Germany). The Kurdish population is estimated to be between 30 and 45 million. Kurds speak the Kurdish languages and the Zaza–Gorani languages, which belong to the Western Iranian branch of the Iranian languages. After World War I and the defeat of the Ottoman Empire, the victorious Western allies made provision for a Kurdish state in the 1920 Treaty of Sèvres. However, that promise was broken three years later, when the Treaty of Lausanne set the boundaries of modern Turkey and made no s ...

International Mathematics Competition For University Students
The International Mathematics Competition (IMC) for University Students is an annual mathematics competition open to all undergraduate students of mathematics. Participating students are expected to be at most twenty three years of age at the time of the IMC. The IMC is primarily a competition for individuals, although most participating universities select and send one or more teams of students. The working language is English. The IMC is a residential competition and all student participants are required to stay in the accommodation provided by the organisers. It aims to provide a friendly, comfortable and secure environment for university mathematics students to enjoy mathematics with their peers from all around the world, to broaden their world perspective and to be inspired to set mathematical goals for themselves that might not have been previously imaginable or thought possible. Notably, in 2018 Caucher Birkar (born Fereydoun Derakhshani), an Iranian Kurdish mathematician, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
