Norair Arakelian
Norair Unanovich Arakelian (often cited as Arakelyan) ( hy, Նորայր Հունանի Առաքելյան born 17 July 1936) is an Armenian and Soviet mathematician, specializing in approximation theory and complex analysis. He is known for Arakelian's approximation theorem. Also, on the base of his approximation theory results, Arakelian has disproved an old conjecture of Rolf Nevanlinna from the value distribution theory. This and other his results Arakelian has presented at the International Congress of Mathematicians at Nice in 1970. Education and career Born in the village of Megrashen (now Armenia), Arakelian enrolled at Yerevan State University (YSU) in 1953 and graduated there in 1958. In 1962 he received his Ph.D. (Russian candidate degree) from YSU with thesis ''Uniform and tangential approximations by entire functions in the complex domain''. From 1959 to 1980 he was Docent of the Chair of Function Theory of YSU. In 1970 he received his doctorate of science (Russian ...

Arakelyan's Theorem
In mathematics, Arakelyan's theorem is a generalization of Mergelyan's theorem from compact subsets of an open subset of the complex plane to relatively closed subsets of an open subset. Theorem Let Ω be an open subset of \Complex and ''E'' a relatively closed subset of Ω. By Ω* is denoted the Alexandroff compactification of Ω. Arakelyan's theorem states that for every ''f'' continuous in ''E'' and holomorphic in the interior of ''E'' and for every ''ε'' > 0 there exists ''g'' holomorphic in Ω such that , ''g'' − ''f'', < ''ε'' on ''E'' if and only if Ω* \ ''E'' is connected and locally connected.

Armenia
Armenia (), , group=pron officially the Republic of Armenia,, is a landlocked country in the Armenian Highlands of Western Asia.The UNbr>classification of world regions places Armenia in Western Asia; the CIA World Factbook , , and ''Oxford Reference Online'' also place Armenia in Asia. It is a part of the Caucasus region; and is bordered by Turkey to the west, Georgia to the north, the Lachin corridor (under a Russian peacekeeping force) and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and the financial center. Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The first Armenian state of Urartu was established in 860 BC, and by the 6th century BC it was replaced by the Satrapy of Armenia. The Kingdom of Armenia reached its height under Tigranes the Great in the 1st century BC and in the year 301 became the first state in the world to adopt ...

Yerevan State University
Yerevan State University (YSU; hy, Երևանի Պետական Համալսարան, ԵՊՀ, ''Yerevani Petakan Hamalsaran''), also simply University of Yerevan, is the oldest continuously operating public university in Armenia. Founded in 1919, it is the largest university in the country. It is thus informally known as Armenia's "mother university" (Մայր ԲՈւՀ, ''Mayr Buh''). Of its 3,150 employees, 1,190 comprise the teaching staff, which includes 25 academicians, 130 professors, 700 docents (associate professors), and 360 assistant lecturers. The university has 400 researchers, 1,350 post-graduate students, and 8,500 undergraduates, including 300 students from abroad. Instruction is in Armenian, but instruction in Russian or English for foreign students is available as needed. The academic year is from September 1 through June 30.

Invited Speaker At The International Congress Of Mathematicians
This is a list of International Congresses of Mathematicians Plenary and Invited Speakers. Being invited to talk at an International Congress of Mathematicians has been called "the equivalent, in this community, of an induction to a hall of fame." The current list of Plenary and Invited Speakers presented here is based on the ICM's post-WW II terminology, in which the one-hour speakers in the morning sessions are called "Plenary Speakers" and the other speakers (in the afternoon sessions) whose talks are included in the ICM published proceedings are called "Invited Speakers". In the pre-WW II congresses the Plenary Speakers were called "Invited Speakers". By congress year 1897, Zürich * Jules Andrade * Léon Autonne *Émile Borel * N. V.

Lenin Komsomol Prize
Lenin Komsomol Prize () was a Soviet annual award for the best works in science, engineering, literature or art carried out by young authors of age not exceeding 33 years. Komsomol was the abbreviated name of The Communist Union of Youth (Russian: Коммунистический союз молодёжи; hence Ком-со-мол, Kom-so-mol). The award was instituted by the Central Committee of VLKSM in March 1966. The reason for the selection of this particular age threshold is unclear (the age threshold for Komsomol membership is 28). The coincidence of the upper threshold of 33 with the "age of Christ" was a matter of jokes. Symbolically, the first winner of this award in the Soviet Union was writer Nikolay Ostrovsky (who had died aged 32 in 1936). In addition to the all-Union prize, Union republics had republican versions of the prize, named respectively, e.g., Belarus Belarus,, , ; alternatively and formerly known as Byelorussia (from Russian ). officially the R ...

21st-century Armenian Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor ...

Approximation Theorists
An approximation is anything that is intentionally similar but not exactly equal to something else. Etymology and usage The word ''approximation'' is derived from Latin ''approximatus'', from ''proximus'' meaning ''very near'' and the prefix ''ad-'' (''ad-'' before ''p'' becomes ap- by assimilation) meaning ''to''. Words like ''approximate'', ''approximately'' and ''approximation'' are used especially in technical or scientific contexts. In everyday English, words such as ''roughly'' or ''around'' are used with a similar meaning. It is often found abbreviated as ''approx.'' The term can be applied to various properties (e.g., value, quantity, image, description) that are nearly, but not exactly correct; similar, but not exactly the same (e.g., the approximate time was 10 o'clock). Although approximation is most often applied to numbers, it is also frequently applied to such things as mathematical functions, shapes, and physical laws. In science, approximation can refer to ...
