Cristian Dumitru Popescu
Cristian Dumitru Popescu (born 1964) is a Romanian-American mathematician at the University of California, San Diego. His research interests are in algebraic number theory, and in particular, in special values of L-functions. Education and career The son of historian Dumitru Micu Popescu and biologist Rodica Jerișteanu, Popescu was born in 1964 in Novaci, Gorj County. After completing his undergraduate studies at the Faculty of Mathematics of the University of Bucharest, he obtained his Ph.D. from the Ohio State University in 1996, with thesis "On a refined Stark conjecture for function fields" written under the direction of Karl Rubin. He became a professor at Johns Hopkins University, after which he moved to his current position as a professor at UC San Diego. Research contributions Popescu formulated and proved function field versions of the Gras conjectures and Rubin's integral refinement of the abelian Stark conjectures. He has also made important contributions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novaci, Romania
Novaci is a town in Gorj County, Oltenia, Romania, situated at the foothills of the Parâng Mountains, on the river Gilort. It administers four villages: Bercești, Hirișești, Pociovaliștea, and Sitești. The river traditionally divided the Oltenian settlement of ''Novacii Români'' from ''Novacii Străini'', populated mainly by shepherds coming from over the mountains, from Sibiu County in Transylvania. The differences between the two segments of the town are obvious in the traditional vernacular architecture: the low fences of Oltenia are replaced by tall gates and hidden-away courtyards in the Novacii Străini. The population has been steadily decreasing since the 1990s, mainly because of the migration of the young, educated inhabitants to bigger cities. Only from Novaci, passing the Transalpina (DN67C) road is Rânca ( altitude), a newly developed resort surrounded by mountain peaks and tremendous beauty. From this place is a view of the Parângu Mare peak and whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwasawa's Main Conjecture
In mathematics, the main conjecture of Iwasawa theory is a deep relationship between ''p''-adic ''L''-functions and ideal class groups of cyclotomic fields, proved by Kenkichi Iwasawa for primes satisfying the Kummer–Vandiver conjecture and proved for all primes by . The Herbrand–Ribet theorem and the Gras conjecture are both easy consequences of the main conjecture. There are several generalizations of the main conjecture, to totally real fields,, CM fields, elliptic curves, and so on. Motivation was partly motivated by an analogy with Weil's description of the zeta function of an algebraic curve over a finite field in terms of eigenvalues of the Frobenius endomorphism on its Jacobian variety. In this analogy, * The action of the Frobenius corresponds to the action of the group Γ. * The Jacobian of a curve corresponds to a module ''X'' over Γ defined in terms of ideal class groups. * The zeta function of a curve over a finite field corresponds to a ''p''-adic '' ...

People From Gorj County
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Institute Of Mathematics Of The Romanian Academy
The "Simion Stoilow" Institute of Mathematics of the Romanian Academy is a research institute in Bucharest, Romania. It is affiliated with the Romanian Academy, and it is named after Simion Stoilow, one of its founders. History On December 29, 1945, a group of twenty Romanian mathematicians from various institutions in Bucharest led by Dimitrie Pompeiu held a meeting at the University of Bucharest to establish the ''Institute of Mathematical Sciences'' with the aim of "promoting scientific research in mathematical sciences, through communications, talks, publications, congresses, and other means proper to this aim". This group also included Dan Barbilian, Alexandru Froda, Alexandru Ghica, Gheorghe Mihoc, Grigore Moisil, Miron Nicolescu, Octav Onicescu, Stoilow, Gabriel Sudan, Victor Vâlcovici, and Gheorghe Vrănceanu. In January 1946 they registered the Institute as a legal person, specifically an NGO, with the Ilfov County Court. On June 9, 1948 the new Commun ...

American Mathematical Society
The American Mathematical Society (AMS) is an association of professional mathematicians dedicated to the interests of mathematical research and scholarship, and serves the national and international community through its publications, meetings, advocacy and other programs. The society is one of the four parts of the Joint Policy Board for Mathematics and a member of the Conference Board of the Mathematical Sciences. History The AMS was founded in 1888 as the New York Mathematical Society, the brainchild of Thomas Fiske, who was impressed by the London Mathematical Society on a visit to England. John Howard Van Amringe became the first president while Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance over concerns about competing with the '' American Journal of Mathematics''. The result was the ''Bulletin of the American Mathematical Society'', with Fiske as editor-in-chief. The de facto journal, as intended, was influentia ...

Romanian Academy
The Romanian Academy ( ) is a cultural forum founded in Bucharest, Romania, in 1866. It covers the scientific, artistic and literary domains. The academy has 181 active members who are elected for life. According to its bylaws, the academy's main goals are the cultivation of Romanian language and Romanian literature, the study of the national history of Romania and research into major scientific domains. Some of the academy's fundamental projects are the Romanian language dictionary ('' Dicționarul explicativ al limbii române''), the dictionary of Romanian literature, and the treatise on the history of the Romanian people. History On the initiative of C. A. Rosetti, the Academy was founded on April 1, 1866, as ''Societatea Literară Română''. The founding members were illustrious members of the Romanian society of the age. The name changed to ''Societatea Academică Romînă'' in 1867, and finally to ''Academia Română'' in 1879, during the reign of Carol I. The foun ...
