Ciprian Foias
Ciprian Ilie Foiaș (20 July 1933 – 22 March 2020) was a Romanian-American mathematician. He was awarded the Norbert Wiener Prize in Applied Mathematics in 1995, for his contributions in operator theory. Education and career Born in Reșița, Romania, Foias studied mathematics at the University of Bucharest. He completed his dissertation in 1957, but was not allowed to defend his thesis by the Communist government until 1962. He received his doctorate in 1962 under supervision of Miron Nicolescu. Foias defected to France following his lecture at the International Congress of Mathematicians in 1978. He later emigrated to the United States. Foias taught at his alma mater (1966–1979), Paris-Sud 11 University (1979–1983), and Indiana University (1983 until retirement). Beginning in 2000, he was a teacher and researcher at Texas A&M University, where he was a Distinguished Professor. The Foias constant is named after him. Foias is listed as an ISI highly cited researcher. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reșița
Reșița (; german: link=no, Reschitz; hu, Resicabánya; hr, Ričica; cz, Rešice; sr, Решица/Rešica; tr, Reşçe) is a city in western Romania and the capital of Caraș-Severin County. It is located in the Banat region. The city had a population of 73,282 in 2011. Etymology The name of ''Reșița'' might come from the Latin ''recitia'', meaning "cold spring", as the historian Nicolae Iorga once suggested, presuming that the Romans gave this name to Resita, from a water spring on the Doman valley. A much more plausibile version, according to Iorgu Iordan, would be that the name is actually coming from a Slavic word: people living in the neighbouring village of Carașova 15 km away, referring to this place, that in those days was a similar village to theirs, as being "u rečice" (at the creek). It can also be noted that almost all Slavic countries have places with the name of Rečice (pronounced Recițe in Romanian). History Historically, the town has its ...

Doctorate
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals d ...

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 was the first president and Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance, due to 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 influential in in ...

Commutant Lifting Theorem
In operator theory, the commutant lifting theorem, due to Sz.-Nagy and Foias, is a powerful theorem used to prove several interpolation results. Statement The commutant lifting theorem states that if T is a contraction on a Hilbert space H, U is its minimal unitary dilation acting on some Hilbert space K (which can be shown to exist by Sz.-Nagy's dilation theorem), and R is an operator on H commuting with T, then there is an operator S on K commuting with U such that :R T^n = P_H S U^n \vert_H \; \forall n \geq 0, and :\Vert S \Vert = \Vert R \Vert. Here, P_H is the projection from K onto H. In other words, an operator from the commutant of ''T'' can be "lifted" to an operator in the commutant of the unitary dilation of ''T''. Applications The commutant lifting theorem can be used to prove the left Nevanlinna-Pick interpolation theorem, the Sarason interpolation theorem In mathematics complex analysis, the Sarason interpolation theorem, introduced by , is a generalizati ...

Béla Szőkefalvi-Nagy
Béla Szőkefalvi-Nagy (29 July 1913, Kolozsvár – 21 December 1998, Szeged) was a Hungarian mathematician. His father, Gyula Szőkefalvi-Nagy was also a famed mathematician. Szőkefalvi-Nagy collaborated with Alfréd Haar and Frigyes Riesz, founders of the Szegedian school of mathematics. He contributed to the theory of Fourier series and approximation theory.

ISI Highly Cited Researcher
The Institute for Scientific Information (ISI) was an academic publishing service, founded by Eugene Garfield in Philadelphia in 1956. ISI offered scientometric and bibliographic database services. Its specialty was citation indexing and analysis, a field pioneered by Garfield. Services ISI maintained citation databases covering thousands of academic journals, including a continuation of its longtime print-based indexing service the Science Citation Index (SCI), as well as the Social Sciences Citation Index (SSCI) and the Arts and Humanities Citation Index (AHCI). All of these were available via ISI's Web of Knowledge database service. This database allows a researcher to identify which articles have been cited most frequently, and who has cited them. The database provides some measure of the academic impact of the papers indexed in it, and may increase their impact by making them more visible and providing them with a quality label. Some anecdotal evidence suggests that appeari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foias Constant
In mathematical analysis, the Foias constant is a real number named after Ciprian Foias. It is defined in the following way: for every real number ''x''1 > 0, there is a sequence defined by the recurrence relation In mathematics, a recurrence relation is an equation according to which the nth term of a sequence of numbers is equal to some combination of the previous terms. Often, only k previous terms of the sequence appear in the equation, for a parameter ... : x_ = \left( 1 + \frac \right)^n for ''n'' = 1, 2, 3, .... The Foias constant is the unique choice ''α'' such that if ''x''1 = ''α'' then the sequence diverges to infinity. For all other values of ''x''1, the sequence is divergent as well, but it has two accumulation points: 1 and infinity.Ewing, J. and Foias, C. "An Interesting Serendipitous Real Number."
