Ciprian Foiaș
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, Foiaș 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 because his father, a respected physician, had been sent to a forced labor camp after the communists came to power. He received his doctorate in 1962 from the Institute of Mathematics of the Romanian Academy (IMAR) under supervision of Miron Nicolescu. Foias began teaching at the University of Bucharest in 1954. From 1958 to 1978 he was a researcher at IMAR, and from 1966 to 1978 he was a professor in the Faculty of Mathematics at the University of Bucharest. In recognition of his growing international reputation, he was named '' doctor docent'' in 1968. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reșița
Reșița (; ; ; ; ; ; ) 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 58,393 in 2021. It administers six villages: Câlnic (''Kölnök''), Cuptoare (''Kuptore''), Doman (''Domány''), Moniom (''Monyó''), Secu (''Székul''; ''Sekul'') and Țerova (''Krassócser''). Etymology The name of ''Reșița'' might come from the Latin ''recitia'', meaning "cold spring", as the historian Nicolae Iorga once suggested, presuming that the Ancient Rome, Romans gave this name to Resita, from a water spring on the Doman River, Doman valley. A much more plausibile version, according to Iorgu Iordan, would be that the name is actually coming from a Slavic languages, 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 co ... [...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 : 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." In ''Finite versus Infinite: Contributions to an Eternal Dilemma'' (Ed. C. Caluse and G. Păun). London: Springer-Verlag, pp. 119–126, 2000. Numerically, it is : \alpha = 1.187452351126501\ldots. No closed form for the constant is known. When ''x''1 = ''α'' then the growth rate of the sequence (''x''''n'') is given by the limit : \lim_ x_n \fracn = 1, wher ...

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. His most important achievements were made in functional analysis, especially, in the theory of Hilbert space operators. He was editor-in-chief of the '' Zentralblatt für Mathematik'', the '' Acta Scientiarum Mathematicarum'', and the '' Analysis Mathematica''. He was awarded the Kossuth Prize in 1953, along with his co-author F. Riesz, for his book ''Leçons d'analyse fonctionnelle.'' He was awarded the Lomonosov Medal in 1979. The Béla Szőkefalvi-Nagy Medal honoring his memory is awarded yearly by Bolyai Institute. His books * Béla Szőkefalvi-Nagy: ''Spektraldarstellung linearer Transformationen des Hi ...

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the IMU Abacus Medal (known before 2022 as the Nevanlinna Prize), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

Docent
The term "docent" is derived from the Latin word , which is the third-person plural present active indicative of ('to teach, to lecture'). Becoming a docent is often referred to as habilitation or doctor of science and is an academic qualification that shows that the holder is qualified to be employed at the level of associate or full professor. The title of "docent" is conferred by some European universities to denote a specific academic appointment within a set structure of academic ranks at or below the full professor rank, similar to a British readership, a French (MCF), and equal to or above the title of ''assistant professor''. Docent is the highest academic title in several countries, and the qualifying criteria are research output that corresponds to 3–5 doctoral dissertations, supervision of PhD students, and experience in teaching at the undergraduate and graduate level. Docent is also used at some (mainly German) universities generically for a person who h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Doctorate
A doctorate (from Latin ''doctor'', meaning "teacher") or doctoral degree is a postgraduate 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. Many universities also award honorary doctorates to individuals deemed worthy of special recognition, either for scholarly work or other contributions to the university or society. History Middle Ages The term ''doctor'' derives from Latin, meaning "teacher" or "instructor". The doctorate (Latin: ''doctoratus'') appeared in medieval Europe as a license to teach Latin (''licentia docendi'') at a university. Its ...

Labor Camp
A labor camp (or labour camp, see British and American spelling differences, spelling differences) or work camp is a detention facility where inmates are unfree labour, forced to engage in penal labor as a form of punishment. Labor camps have many common aspects with slavery and with prisons (especially prison farms). Conditions at labor camps vary widely depending on the operators. Convention no. 105 of the United Nations International Labour Organization (ILO), adopted internationally on 27 June 1957, intended to abolish camps of forced labor. In the 20th century, a new category of labor camps developed for the imprisonment of millions of people who were not criminals ''per se'', but political opponents (real or imagined) and various so-called undesirables under communist and fascist regimes. Precursors Early-modern states could exploit convicts by combining prison and useful work in manning their galleys. This became the sentence of many Christian captives in the Ottoman ...
