Evgenii Nikishin
Evgenii Mikhailovich Nikishin (Евгений Михайлович Никишин; 23 June 1945, in Penza Oblast – 17 December 1986) was a Russian mathematician, who specialized in harmonic analysis. Biography Nikishin, at age of 24, earned his candidate doctorate at Moscow State University, becoming the youngest Candidate Doctorate in a history of MSU and in 1971 his habilitation (Russian doctorate) at the Steklov Institute under Pyotr Ulyanov (1928–2006). In 1977 he became a professor at Moscow State University, where he remained until his death after a long battle with cancer. He worked on approximation theory, especially Padé approximants. Nikishin systems of functions are named after him. Also named in his honour is the Nikishin-Stein factorisation theorem, which is a 1970 generalization by Nikishin of the Stein factorisation theorem. Nikishin also did research on rational approximations in number theory and wrote a monograph on such approximations in a unified appro ...

Lenin Komsomol Prize
Lenin Komsomol Prize () was a Soviet annual award for the best works in science, engineering, literature or art carried out by young authors of age not exceeding 33 years. Komsomol was the abbreviated name of The Communist Union of Youth (Russian: Коммунистический союз молодёжи; hence Ком-со-мол, Kom-so-mol). The award was instituted by the Central Committee of VLKSM in March 1966. The reason for the selection of this particular age threshold is unclear (the age threshold for Komsomol membership is 28). The coincidence of the upper threshold of 33 with the "age of Christ" was a matter of jokes. Symbolically, the first winner of this award in the Soviet Union was writer Nikolay Ostrovsky (who had died aged 32 in 1936). In addition to the all-Union prize, Union republics had republican versions of the prize, named respectively, e.g., Belarus Belarus,, , ; alternatively and formerly known as Byelorussia (from Russian ). officially the R ...

Harmonic Analysis
Harmonic analysis is a branch of mathematics concerned with the representation of Function (mathematics), functions or signals as the Superposition principle, superposition of basic waves, and the study of and generalization of the notions of Fourier series and Fourier transforms (i.e. an extended form of Fourier analysis). In the past two centuries, it has become a vast subject with applications in areas as diverse as number theory, representation theory, signal processing, quantum mechanics, tidal analysis and neuroscience. The term "harmonics" originated as the Ancient Greek word ''harmonikos'', meaning "skilled in music". In physical eigenvalue problems, it began to mean waves whose frequencies are Multiple (mathematics), integer multiples of one another, as are the frequencies of the Harmonic series (music), harmonics of music notes, but the term has been generalized beyond its original meaning. The classical Fourier transform on R''n'' is still an area of ongoing research, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Padé Approximant
In mathematics, a Padé approximant is the "best" approximation of a function near a specific point by a rational function of given order. Under this technique, the approximant's power series agrees with the power series of the function it is approximating. The technique was developed around 1890 by Henri Padé, but goes back to Georg Frobenius, who introduced the idea and investigated the features of rational approximations of power series. The Padé approximant often gives better approximation of the function than truncating its Taylor series, and it may still work where the Taylor series does not converge. For these reasons Padé approximants are used extensively in computer calculations. They have also been used as auxiliary functions in Diophantine approximation and transcendental number theory, though for sharp results ad hoc methods— in some sense inspired by the Padé theory— typically replace them. Since Padé approximant is a rational function, an artificial singul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
