Abstract Algebra
In mathematics, more specifically algebra, abstract algebra or modern algebra is the study of algebraic structures. Algebraic structures include groups, rings, fields, modules, vector spaces, lattices, and algebras over a field. The term ''abstract algebra'' was coined in the early 20th century to distinguish this area of study from older parts of algebra, and more specifically from elementary algebra, the use of variables to represent numbers in computation and reasoning. Algebraic structures, with their associated homomorphisms, form mathematical categories. Category theory is a formalism that allows a unified way for expressing properties and constructions that are similar for various structures. Universal algebra is a related subject that studies types of algebraic structures as single objects. For example, the structure of groups is a single object in universal algebra, which is called the ''variety of groups''. History Before the nineteenth century, algebra meant ...

National Liberation Committee
The National Liberation Committee ( it, Comitato di Liberazione Nazionale, CLN) was a political umbrella organization and the main representative of the Italian resistance movement fighting against Nazi Germany’s forces during the German occupation of Italy in the aftermath of the armistice of Cassibile, while simultaneously fighting against Italian Fascists during the Italian Civil War. It was a multi-party entity, whose members were united by their anti-fascism. The CLN coordinated and directed the Italian resistance and was subdivided into the Central Committee for National Liberation (CCLN) based in Rome and the later National Liberation Committee for Northern Italy (CLNAI) based in Milan. History The CLN was formed on 9 September 1943, following Italy's armistice and Germany's invasion of the country. The member parties were the Italian Communist Party, the Italian Socialist Party, the Action Party, the Christian Democracy, the Labour Democratic Party, and the Italia ...

Giustizia E Libertà
Giustizia e Libertà (; en, Justice and Freedom) was an Italian anti-fascist resistance movement, active from 1929 to 1945.James D. Wilkinson (1981). ''The Intellectual Resistance Movement in Europe''. Harvard University Press. p. 224. The movement was cofounded by Carlo Rosselli, Ferruccio Parri, who later became Prime Minister of Italy, and Sandro Pertini, who became President of Italy, were among the movement's leaders. The movement's members held various political beliefs but shared a belief in active, effective opposition to fascism, compared to the older Italian anti-fascist parties. ''Giustizia e Libertà'' also made the international community aware of the realities of fascism in Italy, thanks to the work of Gaetano Salvemini. Italian anti-fascist organization (1929–1940) Foundation The anti-fascist organisation ''Giustizia e Libertà'' was established in 1929 by the Italian refugees Riccardo Bauer, Carlo Rosselli, Emilio Lussu, Alberto Tarchiani, and Ernest ...

Partito D’Azione
The Action Party ( it, Partito d'Azione, PdA) was a liberal-socialist political party in Italy. The party was anti-fascist and republican. Its prominent leaders were Carlo Rosselli, Ferruccio Parri, Emilio Lussu and Ugo La Malfa. Other prominent members included Leone Ginzburg, Ernesto de Martino, Norberto Bobbio, Riccardo Lombardi, Vittorio Foa and the Nobel-winning poet Eugenio Montale. History Founded in July 1942 by former militants of ''Giustizia e Libertà'' (Justice and Freedom), liberal-socialists and democrats. Ideologically, they were heirs to the liberal socialism of Carlo Rosselli and to Piero Gobetti's liberal revolution, whose writings rejected Marxist economic determinism and aimed at the overcoming of class struggle and for a new shape of socialism, respect for civil liberty and for radical change in both the social and the economic structure of Italy. From January 1943, it published a clandestine newspaper, '' L'Italia Libera'' (''Free Italy''), edited by Leon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florence
Florence ( ; it, Firenze ) is a city in Central Italy and the capital city of the Tuscany region. It is the most populated city in Tuscany, with 383,083 inhabitants in 2016, and over 1,520,000 in its metropolitan area.Bilancio demografico anno 2013, datISTAT/ref> Florence was a centre of medieval European trade and finance and one of the wealthiest cities of that era. It is considered by many academics to have been the birthplace of the Renaissance, becoming a major artistic, cultural, commercial, political, economic and financial center. During this time, Florence rose to a position of enormous influence in Italy, Europe, and beyond. Its turbulent political history includes periods of rule by the powerful Medici family and numerous religious and republican revolutions. From 1865 to 1871 the city served as the capital of the Kingdom of Italy (established in 1861).

Algebraic Geometry
Algebraic geometry is a branch of mathematics, classically studying zeros of multivariate polynomials. Modern algebraic geometry is based on the use of abstract algebraic techniques, mainly from commutative algebra, for solving geometrical problems about these sets of zeros. The fundamental objects of study in algebraic geometry are algebraic varieties, which are geometric manifestations of solutions of systems of polynomial equations. Examples of the most studied classes of algebraic varieties are: plane algebraic curves, which include lines, circles, parabolas, ellipses, hyperbolas, cubic curves like elliptic curves, and quartic curves like lemniscates and Cassini ovals. A point of the plane belongs to an algebraic curve if its coordinates satisfy a given polynomial equation. Basic questions involve the study of the points of special interest like the singular points, the inflection points and the points at infinity. More advanced questions involve the topology of the ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Analytical Geometry
In classical mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry. Analytic geometry is used in physics and engineering, and also in aviation, rocketry, space science, and spaceflight. It is the foundation of most modern fields of geometry, including algebraic, differential, discrete and computational geometry. Usually the Cartesian coordinate system is applied to manipulate equations for planes, straight lines, and circles, often in two and sometimes three dimensions. Geometrically, one studies the Euclidean plane (two dimensions) and Euclidean space. As taught in school books, analytic geometry can be explained more simply: it is concerned with defining and representing geometric shapes in a numerical way and extracting numerical information from shapes' numerical definitions and representations. That the algebra of the real numbers can be employed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Florence
The University of Florence (Italian: ''Università degli Studi di Firenze'', UniFI) is an Italian public research university located in Florence, Italy. It comprises 12 schools and has around 50,000 students enrolled. History The first university in Florence was the Studium Generale, which was established by the Florentine Republic in 1321. The Studium was recognized by Pope Clement VI in 1349, and authorized to grant regular degrees. The Pope also established that the first Italian faculty of theology would be in Florence. The Studium became an imperial university in 1364, but was moved to Pisa in 1473 when Lorenzo the Magnificent gained control of Florence. Charles VIII moved it back from 1497 to 1515, but it was moved to Pisa again when the Medici family returned to power. The modern university dates from 1859, when a group of disparate higher-studies institutions grouped together in the Istituto di Studi Pratici e di Perfezionamento, which a year later was recognized as ...
