Eléna Wexler-Kreindler
Eléna Wexler-Kreindler (15 October 1931 – August 1992) was a Romanian mathematician. She spent most of her professional career in France, where she specialized in modern algebra and studied the Ore extensions, the theory of the Filtration (mathematics), filtration of Ring (mathematics), rings, or algebraic Localization of a ring, microlocalisation. Career Kreindler was born on 15 October 1931 in Brăila, Romania into a Jewish family. She obtained in 1951 a fellowship and spent the next four years in the USSR studying mathematics at the Ural State University, located in Sverdlovsk (nowadays Yekaterinburg). In 1955, she completed a master thesis on ''"Multiplicative Lattices with Additive Basis"'' under the supervision of Petr Grigor'evich Kontorovich, before returning to Bucharest to join the faculty of Mathematics at the Politehnica University of Bucharest, Polytechnic Institute of Bucharest. Next to her duties as assistant professor, she continued with her research in the fiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ore Extension
In mathematics, especially in the area of algebra known as ring theory, an Ore extension, named after Øystein Ore, is a special type of a ring extension whose properties are relatively well understood. Elements of a Ore extension are called Ore polynomials. Ore extensions appear in several natural contexts, including skew and differential polynomial rings, group algebras of polycyclic groups, universal enveloping algebras of solvable Lie algebras, and coordinate rings of quantum groups. Definition Suppose that ''R'' is a (not necessarily commutative) ring, \sigma \colon R \to R is a ring homomorphism, and \delta\colon R\to R is a ''σ''-derivation of ''R'', which means that \delta is a homomorphism of abelian groups satisfying : \delta(r_1 r_2) = \sigma(r_1)\delta(r_2)+\delta(r_1)r_2. Then the Ore extension R ;\sigma,\delta/math>, also called a skew polynomial ring, is the noncommutative ring obtained by giving the ring of polynomials R /math> a new multiplication, su ...

People From Brăila
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of Pierre And Marie Curie University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pierre And Marie Curie University
Pierre and Marie Curie University ( , UPMC), also known as Paris VI, was a public research university in Paris, France, from 1971 to 2017. The university was located on the Jussieu Campus in the Latin Quarter of the 5th arrondissement of Paris, France. UPMC merged with Paris-Sorbonne University into a new combined Sorbonne University. History Paris VI was one of the inheritors of the faculty of Sciences of the University of Paris, which was divided into several universities in 1970 after the student protests of May 1968. In 1971, the five faculties of the former University of Paris (Paris VI as the Faculty of Sciences) were split and then re-formed into thirteen universities by the Faure Law. The campus of Paris VI was built in the 1950s and 1960s, on a site previously occupied by wine storehouses. The Dean, Marc Zamanski, saw the Jussieu campus standing as a tangible symbol of scientific thought in the heart of Paris, with the Faculty of Science, set in the Latin Quarter, ...
