Helmut Röhrl
Helmut Röhrl or Rohrl (born 22 March 1927 in Straubing, died 30 January 2014) was a German mathematician. Besides complex analysis (including among other subjects the Riemann–Hilbert problem), he worked on algebra and category theory and totally convex spaces. In 1964 he edited the new edition of the classic textbook on complex analysis by Adolf Hurwitz and Richard Courant. Röhrl received his doctorate in 1949 at the Ludwig-Maximilians-Universität München under Robert König (and Oskar Perron) with doctoral thesis ''Über Differentialsysteme, welche aus multiplikativen Klassen mit exponentiellen Singularitäten entspringen''published in 3 parts, ''Mathematische Annalen'', vol. 123, 1951, pp. 53–75; vol. 124, 1952, pp. 187–218; vol. 125, 1953, pp. 448–466 and his habilitation in 1953 with habilitation thesis ''Abelsche Integrale auf Riemannschen Flächen endlichen Geschlechts''. He was a docent in mathematics from 1949 to 1951 in Würzburg, from 1951 to 1953 in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straubing
Straubing () is an independent city in Lower Bavaria, southern Germany. It is seat of the district of Straubing-Bogen. Annually in August the Gäubodenvolksfest, the second largest fair in Bavaria, is held. The city is located on the Danube forming the centre of the Gäuboden. History The area of Straubing has been continuously settled since the Neolithic. The conquest by the Romans in 16–14 BC had a dramatic impact on the whole region. Even today many traces of the 400-year Roman occupation can be found: for example, the famous 'Römerschatz' (Roman treasure) which was excavated in 1950 and which is shown in the Gäubodenmuseum. ''Sorviodurum'', as the Romans called it, was an important military support base. After the fall of the Roman Empire Straubing became a centre of settlement of the Bavarii, mostly around St. Peter's Church (built in the 9th century) between Allachbach and Danube. According to the customs of the Bavarii the settlement was named after their leader ''S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvard University
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees.

People From Straubing
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 ...

Hilbert's Twenty-first Problem
The twenty-first problem of the 23 Hilbert problems, from the celebrated list put forth in 1900 by David Hilbert, concerns the existence of a certain class of linear differential equations with specified singular points and monodromic group. Statement The original problem was stated as follows (English translation from 1902): :''Proof of the existence of linear differential equations having a prescribed monodromic group'' :''In the theory of linear differential equations with one independent variable z, I wish to indicate an important problem one which very likely Riemann himself may have had in mind. This problem is as follows: To show that there always exists a linear differential equation of the Fuchsian class, with given singular points and monodromic group. The problem requires the production of n functions of the variable z, regular throughout the complex z-plane except at the given singular points; at these points the functions may become infinite of only finite orde ...

Function Of Several Complex Variables
The theory of functions of several complex variables is the branch of mathematics dealing with complex-valued functions. The name of the field dealing with the properties of function of several complex variables is called several complex variables (and analytic space), that has become a common name for that whole field of study and Mathematics Subject Classification has, as a top-level heading. A function f:(z_1,z_2, \ldots, z_n) \rightarrow f(z_1,z_2, \ldots, z_n) is -tuples of complex numbers, classically studied on the complex coordinate space \Complex^n. As in complex analysis of functions of one variable, which is the case , the functions studied are ''holomorphic'' or ''complex analytic'' so that, locally, they are power series in the variables . Equivalently, they are locally uniform limits of polynomials; or locally square-integrable solutions to the -dimensional Cauchy–Riemann equations. For one complex variable, every domainThat is an open connected subset. (D \subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
