Alexander Givental
Alexander Givental (russian: Александр Борисович Гивенталь) is a Russian-American mathematician working in symplectic topology and singularity theory, as well as their relation to topological string theories. He graduated from Moscow Phys-Math school number 2 (later renamed into Lyceum ) and then the Gubkin Russian State University of Oil and Gas, and he finally his Ph.D. under the supervision of V. I. Arnold in 1987. He emigrated to the USA in 1990. He provided the first proof of the mirror conjecture for Calabi–Yau manifolds that are complete intersections in toric ambient spaces, in particular for quintic hypersurfaces in P4. He is now Professor of Mathematics at the University of California, Berkeley The University of California, Berkeley (UC Berkeley, Berkeley, Cal, or California) is a public land-grant research university in Berkeley, California. Established in 1868 as the University of California, it is the state's first land-grant u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian American
Russian Americans ( rus, русские американцы, r=russkiye amerikantsy, p= ˈruskʲɪje ɐmʲɪrʲɪˈkant͡sɨ) are Americans of full or partial Russian ancestry. The term can apply to recent Russian immigrants to the United States, as well as to those who settled in the 19th-century Russian possessions in northwestern America. Russian Americans comprise the largest Eastern European and East Slavic population in the U.S., the second-largest Slavic population generally, the nineteenth-largest ancestry group overall, and the eleventh-largest from Europe. In the mid-19th century, waves of Russian immigrants fleeing religious persecution settled in the U.S., including Russian Jews and Spiritual Christians. These groups mainly settled in coastal cities, including Alaska, Brooklyn (New York City) on the East Coast, and Los Angeles, San Francisco, and Portland, Oregon, on the West Coast, as well as in Great Lakes cities, such as Chicago and Cleveland.

Hypersurface
In geometry, a hypersurface is a generalization of the concepts of hyperplane, plane curve, and surface. A hypersurface is a manifold or an algebraic variety of dimension , which is embedded in an ambient space of dimension , generally a Euclidean space, an affine space or a projective space. Hypersurfaces share, with surfaces in a three-dimensional space, the property of being defined by a single implicit equation, at least locally (near every point), and sometimes globally. A hypersurface in a (Euclidean, affine, or projective) space of dimension two is a plane curve. In a space of dimension three, it is a surface. For example, the equation :x_1^2+x_2^2+\cdots+x_n^2-1=0 defines an algebraic hypersurface of dimension in the Euclidean space of dimension . This hypersurface is also a smooth manifold, and is called a hypersphere or an -sphere. Smooth hypersurface A hypersurface that is a smooth manifold is called a ''smooth hypersurface''. In , a smooth hypersurface is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of California, Berkeley College Of Letters And Science Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The universit ...

21st-century American Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emper ...

Marina Tsvetaeva
Marina Ivanovna Tsvetaeva (russian: Марина Ивановна Цветаева, p=mɐˈrʲinə ɪˈvanəvnə tsvʲɪˈtaɪvə; 31 August 1941) was a Russian poet. Her work is considered among some of the greatest in twentieth century Russian literature."Tsvetaeva, Marina Ivanovna" ''Who's Who in the Twentieth Century''. Oxford University Press, 1999. She lived through and wrote of the Russian Revolution of 1917 and the Moscow famine that followed it. In an attempt to save her daughter Irina from starvation, she placed her in a state orphanage in 1919, where she died of hunger. Tsvetaeva left Russia in 1922 and lived with her family in increasing poverty in Paris, Berlin and Prague before returning to Moscow in 1939. Her husband Sergei Efron and their daughter Ariadna (Alya) were arrested on espionage charges in 1941; her husband was executed. Tsvetaeva committed suicide in 1941.

Quintic Equation
In algebra, a quintic function is a function of the form :g(x)=ax^5+bx^4+cx^3+dx^2+ex+f,\, where , , , , and are members of a field, typically the rational numbers, the real numbers or the complex numbers, and is nonzero. In other words, a quintic function is defined by a polynomial of degree five. Because they have an odd degree, normal quintic functions appear similar to normal cubic functions when graphed, except they may possess one additional local maximum and one additional local minimum. The derivative of a quintic function is a quartic function. Setting and assuming produces a quintic equation of the form: :ax^5+bx^4+cx^3+dx^2+ex+f=0.\, Solving quintic equations in terms of radicals (''n''th roots) was a major problem in algebra from the 16th century, when cubic and quartic equations were solved, until the first half of the 19th century, when the impossibility of such a general solution was proved with the Abel–Ruffini theorem. Finding roots of a quintic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
