Vladimir Gerdt
Vladimir P. Gerdt (21 January 1947—January 5, 2021) was a Russian mathematician and a full professor at the Joint Institute for Nuclear Research (JINR) where he was the head of the Group of Algebraic and Quantum Computations. His research interests were concentrated in computer algebra, symbolic and algebraic computations, algebraic and numerical analysis of nonlinear differential equations, polynomial equations, applications to mathematics and physics, and quantum computation with over 210 published articles. Biography Gerdt, who was born in Engels, earned his MSc in theoretical physics from Saratov State University in 1971, his PhD in theoretical and mathematical physics from JINR in 1976, and his D.Sc. in mathematics and computer science from JINR in 1992. He also did graduate studies in theoretical physics at the Lomonosov Moscow State University (1969-1971). After his MSc he worked as an engineer-programmer (1971-1975) and as a junior researcher (1975-1977) at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engels, Saratov Oblast
Engels ( rus, Э́нгельс, p=ˈɛnɡʲɪlʲs), formerly known as Pokrovsk and Kosakenstadt, is a city in Saratov Oblast, Russia. It is a port located on the Volga River across from Saratov, the administrative center of the oblast, and is connected to it with a bridge. It is the second-largest city in Saratov Oblast with a population of . Historically an important center for Volga Germans, the city was known jointly as Pokrovsk in Russian and as Kosakenstadt in German, until it was renamed after Friedrich Engels in 1931. Engels served as the capital of the Volga German Autonomous Soviet Socialist Republic from 1918 to 1941. It was previously known as ''Pokrovska sloboda'' (until 1914), ''Pokrovsk'' (until 1931). History Engels was founded as a sloboda named Pokrovska Sloboda by Ukrainian Chumak settlers in 1747. During the reign of Catherine the Great, ethnic Germans were encouraged to settle in the Volga region and many moved into the town, making it a major center of the ...

Gröbner Basis
In mathematics, and more specifically in computer algebra, computational algebraic geometry, and computational commutative algebra, a Gröbner basis is a particular kind of generating set of an ideal in a polynomial ring over a field . A Gröbner basis allows many important properties of the ideal and the associated algebraic variety to be deduced easily, such as the dimension and the number of zeros when it is finite. Gröbner basis computation is one of the main practical tools for solving systems of polynomial equations and computing the images of algebraic varieties under projections or rational maps. Gröbner basis computation can be seen as a multivariate, non-linear generalization of both Euclid's algorithm for computing polynomial greatest common divisors, and Gaussian elimination for linear systems. Gröbner bases were introduced in 1965, together with an algorithm to compute them (Buchberger's algorithm), by Bruno Buchberger in his Ph.D. thesis. He named them after h ...

The city stands on the Moskva River in Central Russia, with a population estimated at 13.0 million residents within the city limits, over 17 million residents in the urban area, and over 21.5 million residents in the metropolitan area. The city covers an area of , while the urban area covers , and the metropolitan area covers over . Moscow is among the world's largest cities; being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its name. When the Grand Duchy of Moscow evolved into the Tsardom of Russia, Moscow remained the political and economic center for most of the Tsardom's history. When th ...

People From Engels, Saratov Oblast
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Involution (mathematics)
In mathematics, an involution, involutory function, or self-inverse function is a function that is its own inverse, : for all in the domain of . Equivalently, applying twice produces the original value. General properties Any involution is a bijection. The identity map is a trivial example of an involution. Examples of nontrivial involutions include negation (x \mapsto -x), reciprocation (x \mapsto 1/x), and complex conjugation (z \mapsto \bar z) in arithmetic; reflection, half-turn rotation, and circle inversion in geometry; complementation in set theory; and reciprocal ciphers such as the ROT13 transformation and the Beaufort polyalphabetic cipher. The composition of two involutions ''f'' and ''g'' is an involution if and only if they commute: . Involutions on finite sets The number of involutions, including the identity involution, on a set with elements is given by a recurrence relation found by Heinrich August Rothe in 1800: :a_0 = a_1 = 1 and a_n = a_ + ...
