Julius Borcea
Julius Bogdan Borcea (8 June 1968 – 8 April 2009) was a Romanian Swedish mathematician. His scientific work included vertex operator algebra and zero distribution of polynomials and entire functions, via correlation inequalities and statistical mechanics. Biography Born in Bacău, Romania, by a math teacher who instilled in her son's intellect the beauty of mathematics, he studied in 1982-1984 at the Lycée Descartes in Rabat, Morocco, and he completed his Baccalaureat at the Lycée Français Prins Henrik of Copenhagen. In 1987–1989 he attended the Lycée Louis-le-Grand in Paris. He obtained his PhD in Mathematics in 1998, at Lund University, under the direction of Arne Meurman. After defending his PhD thesis in 1998, he embarked in postdoctoral studies at the Mittag-Leffler Institute for six months and at the University of Strasbourg for two years. He was appointed Associate Professor in 2001, and Lecturer in 2005 at Stockholm University. A year later he was granted th ...

Bacău
Bacău ( ; , ; ; ) is the main city in Bacău County, Romania. With a population of 136,087 (as of 2021 census), Bacău is the 14th largest city in Romania. The city is situated in the historical region of Moldavia, at the foothills of the Carpathian Mountains, and on the Bistrița River (which meets the Siret River about to the south of Bacău). The Ghimeș Pass links Bacău to the region of Transylvania. Etymology The town's name, which features in Old Church Slavonic documents as ''Bako'', ''Bakova'' or ''Bakovia'', comes most probably from a personal name of Hungarian origin. Men bearing the name Bakó or Bako are documented in medieval TransylvaniaRădvan 2010, p. 456. and in 15th-century Bulgaria, but according to Victor Spinei the name itself is of Turkicmost probably of Cuman or Pechenegorigin. Nicolae Iorga believes that the city's name is of Hungarian origin (as Adjud and Sascut). Another theory suggests that the town's name has a Slavic origin, pointing ...

George Pólya
George Pólya (; ; December 13, 1887 – September 7, 1985) was a Hungarian-American mathematician. He was a professor of mathematics from 1914 to 1940 at ETH Zürich and from 1940 to 1953 at Stanford University. He made fundamental contributions to combinatorics, number theory, numerical analysis and probability theory. He is also noted for his work in heuristics and mathematics education. He has been described as one of The Martians (scientists), The Martians, an informal category which included one of his most famous students at ETH Zurich, John von Neumann. Life and works Pólya was born in Budapest, Austria-Hungary, to Anna Deutsch and Jakab Pólya, History of the Jews in Hungary, Hungarian Jews who had converted to Christianity in 1886. Although his parents were religious and he was baptized into the Catholic Church upon birth, George eventually grew up to be an agnostic. He received a PhD under Lipót Fejér in 1912, at Eötvös Loránd University. He was a professor o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmond Laguerre
Edmond Nicolas Laguerre (9 April 1834, Bar-le-Duc – 14 August 1886, Bar-le-Duc) was a French mathematician and a member of the Académie des sciences (1885). His main works were in the areas of geometry and complex analysis. He also investigated orthogonal polynomials (see Laguerre polynomials). Laguerre's method is a root-finding algorithm tailored to polynomials. He laid the foundations of a geometry of oriented spheres (Laguerre geometry and Laguerre plane), including the Laguerre transformation or transformation by reciprocal directions.

Piecewise
In mathematics, a piecewise function (also called a piecewise-defined function, a hybrid function, or a function defined by cases) is a function whose domain is partitioned into several intervals ("subdomains") on which the function may be defined differently. Piecewise definition is actually a way of specifying the function, rather than a characteristic of the resulting function itself, as every function whose domain contains at least two points can be rewritten as a piecewise function. The first three paragraphs of this article only deal with this first meaning of "piecewise". Terms like piecewise linear, piecewise smooth, piecewise continuous, and others are also very common. The meaning of a function being piecewise P, for a property P is roughly that the domain of the function can be partitioned into pieces on which the property P holds, but is used slightly differently by different authors. Unlike the first meaning, this is a property of the function itself and not on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operator Theory
In mathematics, operator theory is the study of linear operators on function spaces, beginning with differential operators and integral operators. The operators may be presented abstractly by their characteristics, such as bounded linear operators or closed operators, and consideration may be given to nonlinear operators. The study, which depends heavily on the topology of function spaces, is a branch of functional analysis. If a collection of operators forms an algebra over a field, then it is an operator algebra. The description of operator algebras is part of operator theory. Single operator theory Single operator theory deals with the properties and classification of operators, considered one at a time. For example, the classification of normal operators in terms of their spectra falls into this category. Spectrum of operators The spectral theorem is any of a number of results about linear operators or about matrices. In broad terms the spectral theorem provides cond ...
