Gregory Freiman
Gregory Abelevich Freiman (; 3 July 1926 – 19 September 2024) was a Russian and Israeli mathematician known for his work in additive number theory, in particular, for proving Freiman's theorem. He was a Professor Emeritus in Tel Aviv University. Biography Freiman was born in Kazan on 3 July 1926. He graduated from Moscow University in 1949, and obtained his Candidate of Sciences in Kazan University in 1956. From 1956 he worked in Elabuga, and in 1965 he defended his Doctor of Sciences degree under the joint supervision of Alexander Gelfond, Alexey G. Postnikov, and Alexander Buchstab. From 1967 he worked in Vladimir, and later in Kalinin (now Tver). In the 1970s and early 1980s Freiman participated in the refusenik movement. His samizdat Samizdat (, , ) was a form of dissident activity across the Eastern Bloc in which individuals reproduced censored and underground makeshift publications, often by hand, and passed the documents from reader to reader.

Number Theorists
Number theory is a branch of pure mathematics devoted primarily to the study of the integers and arithmetic functions. Number theorists study prime numbers as well as the properties of mathematical objects constructed from integers (for example, rational numbers), or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations ( Diophantine geometry). Questions in number theory can often be understood through the study of analytical objects, such as the Riemann zeta function, that encode properties of the integers, primes or other number-theoretic objects in some fashion (analytic number theory). One may also study real numbers in relation to rational numbers, as for instance how irrational numbers can be approximated by fractions (Diophantine approximation). Number theory is one of the oldest branches of mathematics alongside geometry. One quirk of number theory is that it deals wi ...

Israeli Jews
Israeli Jews or Jewish Israelis ( ) comprise Israel's largest ethnic and religious community. The core of their demographic consists of those with a Jewish identity and their descendants, including ethnic Jews and religious Jews alike. Approximately 46% of the global Jewish population resides in Israel; is uncommon and is offset exponentially by , but those who do emigrate from the country typically relocate to the Western world. As such, the Israeli diaspora is closely tied to the broader Jewish diaspora. The country is widely described as a melting pot for the various Jewish ethnic divisions, primarily consisting of Ashkenazi Jews, Sephardic Jews, and Mizrahi Jews, as well as many smaller Jewish communities, such as the Beta Israel, the Cochin Jews, the Bene Israel, and the Karaite Jews, among others. Likewise, over 25% of Jewish children and 35% of Jewish newborns in Israel are of mixed Ashkenazi and Sephardic or Mizrahi descent, and these figures have been increasing by ...

Russian Jews
The history of the Jews in Russia and areas historically connected with it goes back at least 1,500 years. Jews in Russia have historically constituted a large religious and ethnic diaspora; the Russian Empire at one time hosted the largest population of Jews in the world. Within these territories, the primarily Ashkenazi Jewish communities of many different areas flourished and developed many of modern Judaism's most distinctive theological and cultural traditions, while also facing periods of antisemitic discriminatory policies and persecution, including violent pogroms. Many analysts have noted a "renaissance" in the Jewish community inside Russia since the beginning of the 21st century;Renaissance of Jewish life in Russia November 23, 2001, By John Daniszewski, Chi ...

1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Samizdat
Samizdat (, , ) was a form of dissident activity across the Eastern Bloc in which individuals reproduced censored and underground makeshift publications, often by hand, and passed the documents from reader to reader. The practice of manual reproduction was widespread, because printed texts could be traced back to the source. This was a grassroots practice used to evade official Soviet censorship. Name origin and variations Etymologically, the word ''samizdat'' derives from ''sam'' ( 'self, by oneself') and ''izdat'' (, an abbreviation of , 'publishing house'), and thus means 'self-published'. Ukrainian has a similar term: ''samvydav'' (самвидав), from ''sam'' 'self' and ''vydavnytstvo'' 'publishing house'. The Russian poet Nikolay Glazkov coined a version of the term as a pun in the 1940s when he typed copies of his poems and included the note ''Samsebyaizdat'' (Самсебяиздат, "Myself by Myself Publishers") on the front page. ''Tamizdat'' refers to lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refusenik
Refusenik (, ; alternatively spelled refusnik) was an unofficial term for individuals—typically, but not exclusively, Soviet Jews—who were denied permission to emigrate, primarily to Israel, by the authorities of the Soviet Union and other countries of the Soviet Bloc. The term ''refusenik'' is derived from the "refusal" handed down to a prospective emigrant from the Soviet authorities. In addition to the Jews, broader categories included: *Other ethnicities, such as Volga Germans attempting to leave for Germany, Armenians wanting to join their diaspora, and Greeks forcibly removed by Stalin from Crimea and other southern lands to Siberia. *Members of persecuted religious groups, such as the Ukrainian Greek Catholic Church, Baptists and other Protestant groups, Jehovah's Witnesses, and Russian Mennonites. A typical basis to deny emigration was the alleged association with Soviet state secrets. Some individuals were labelled as foreign spies or potential seditioni ...
