Second Polish Republic
The Second Polish Republic, at the time officially known as the Republic of Poland, was a country in Central Europe, Central and Eastern Europe that existed between 1918 and 1939. The state was established on 6 November 1918, before the end of the First World War. The Second Republic ceased to exist in 1939, when Invasion of Poland, Poland was invaded by Nazi Germany, the Soviet Union and the Slovak Republic (1939–1945), Slovak Republic, marking the beginning of the European theatre of World War II, European theatre of the Second World War. In 1938, the Second Republic was the sixth largest country in Europe. According to the Polish census of 1921, 1921 census, the number of inhabitants was 27.2 million. By 1939, just before the outbreak of World War II, this had grown to an estimated 35.1 million. Almost a third of the population came from minority groups: 13.9% Ruthenians; 10% Ashkenazi Jews; 3.1% Belarusians; 2.3% Germans and 3.4% Czechs and Lithuanians. At the same time, a ...

Shanghai
Shanghai (; , , Standard Mandarin pronunciation: ) is one of the four direct-administered municipalities of the People's Republic of China (PRC). The city is located on the southern estuary of the Yangtze River, with the Huangpu River flowing through it. With a population of 24.89 million as of 2021, Shanghai is the most populous urban area in China with 39,300,000 inhabitants living in the Shanghai metropolitan area, the second most populous city proper in the world (after Chongqing) and the only city in East Asia with a GDP greater than its corresponding capital. Shanghai ranks second among the administrative divisions of Mainland China in human development index (after Beijing). As of 2018, the Greater Shanghai metropolitan area was estimated to produce a gross metropolitan product (nominal) of nearly 9.1 trillion RMB ($1.33 trillion), exceeding that of Mexico with GDP of $1.22 trillion, the 15th largest in the world.

1937 Births
Events January * January 1 – Anastasio Somoza García becomes President of Nicaragua. * January 5 – Water levels begin to rise in the Ohio River in the United States, leading to the Ohio River flood of 1937, which continues into February, leaving 1 million people homeless and 385 people dead. * January 15 – Spanish Civil War: Second Battle of the Corunna Road ends inconclusively. * January 20 – Second inauguration of Franklin D. Roosevelt: Franklin D. Roosevelt is sworn in for a second term as President of the United States.

Rubí Rodríguez
Rubí Elena Rodríguez Moreno is a Chilean mathematician in the department of mathematics and statistics at the University of La Frontera, a founder of the Iberoamerican Congress on Geometry, and the former president of the Chilean Mathematical Society. Her research specialties include complex geometry, Fuchsian groups, Riemann surfaces, and abelian varieties. Education Rodríguez earned a master's degree in mathematics at the in 1975. She completed her Ph.D. in 1981 at Columbia University; her dissertation, ''On Schottky-Type Groups with Applications to Riemann Surfaces with Nodes'', was supervised by Lipman Bers. Career Rodríguez worked for the University of Santiago, Chile, but was dismissed in 1985, during the regime of Augusto Pinochet, for unstated but likely-political reasons. After many colleagues appealed the decision, she was hired by the Federico Santa María Technical University. She was president of the Chilean Mathematical Society from 2006 to 2010. Books Rodrí ...

Math For America
Math for America (MfA) is a nonprofit organization, founded in January 2004 by American billionaire mathematician, hedge fund manager, and philanthropist Jim Simons to promote recruitment and retention of mathematics teachers in New York City secondary schools. History According to Simons, he founded the program to address failures in the US education system to produce students highly qualified in STEM skills and knowledge, which reduces America's ability to compete in the global economy. He perceived the cause of the failure as low quality teachers, and saw that problem in turn as being caused by low salaries, lack of prestige, and lack of support and good training making the job unattractive to qualified candidates, many of whom could get jobs in lucrative fields like quantitative finance Mathematical finance, also known as quantitative finance and financial mathematics, is a field of applied mathematics, concerned with mathematical modeling of financial markets. In general, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kleinian Group
In mathematics, a Kleinian group is a discrete subgroup of the group (mathematics), group of orientation-preserving Isometry, isometries of hyperbolic 3-space . The latter, identifiable with PSL(2,C), , is the quotient group of the 2 by 2 complex number, complex matrix (mathematics), matrices of determinant 1 by their center (group theory), center, which consists of the identity matrix and its product by . has a natural representation as orientation-preserving conformal transformations of the Riemann sphere, and as orientation-preserving conformal transformations of the open unit ball in . The group of Möbius transformation, Möbius transformations is also related as the non-orientation-preserving isometry group of , . So, a Kleinian group can be regarded as a discrete subgroup group action, acting on one of these spaces. History The theory of general Kleinian groups was founded by and , who named them after Felix Klein. The special case of Schottky groups had been studied a ...

Teichmüller Space
In mathematics, the Teichmüller space T(S) of a (real) topological (or differential) surface S, is a space that parametrizes complex structures on S up to the action of homeomorphisms that are isotopic to the identity homeomorphism. Teichmüller spaces are named after Oswald Teichmüller. Each point in a Teichmüller space T(S) may be regarded as an isomorphism class of "marked" Riemann surfaces, where a "marking" is an isotopy class of homeomorphisms from S to itself. It can be viewed as a moduli space for marked Riemann surface#Hyperbolic Riemann surfaces, hyperbolic structure on the surface, and this endows it with a natural topology for which it is homeomorphic to a Ball (mathematics), ball of dimension 6g-6 for a surface of genus g \ge 2. In this way Teichmüller space can be viewed as the orbifold, universal covering orbifold of the Moduli of algebraic curves, Riemann moduli space. The Teichmüller space has a canonical complex manifold structure and a wealth of natural m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
