Gaetano Scorza
Bernardino Gaetano Scorza (29 September 1876, in Morano Calabro – 6 August 1939, in Rome) was an Italian mathematician working in algebraic geometry, whose work inspired the theory of Scorza varieties In mathematics, a ''k''-Scorza variety is a smooth projective variety, of maximal dimension among those whose ''k''–1 secant varieties are not the whole of projective space. Scorza varieties were introduced and classified by , who named them after ....

Morano Calabro
Morano Calabro ( Moranese: ) is a town and '' comune'' in the province of Cosenza in the Calabria region of southern Italy. It was the birthplace of mathematician Gaetano Scorza. Geography The municipality borders with Castrovillari (the nearest town), Mormanno, Rotonda, San Basile, Saracena, Terranova di Pollino and Viggianello. Campotenese Its '' frazione'' (civil parish), the village of Campotenese, is located on a mountain pass at 1,015 amsl. A tourist site, the village is best known for the Battle of Campo Tenese (1806) between the First French Empire and the Kingdom of Naples The Kingdom of Naples ( la, Regnum Neapolitanum; it, Regno di Napoli; nap, Regno 'e Napule), also known as the Kingdom of Sicily, was a state that ruled the part of the Italian Peninsula south of the Papal States between 1282 and 1816.

Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically b ...

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 topo ...

Scorza Varieties
In mathematics, a ''k''-Scorza variety is a smooth projective variety, of maximal dimension among those whose ''k''–1 secant varieties are not the whole of projective space. Scorza varieties were introduced and classified by , who named them after Gaetano Scorza. The special case of 2-Scorza varieties are sometimes called Severi varieties, after Francesco Severi. Classification Zak showed that ''k''-Scorza varieties are the projective varieties of the rank 1 matrices of rank ''k'' simple Jordan algebras. Severi varieties The Severi varieties are the non-singular varieties of dimension ''n'' (even) in P''N'' that can be isomorphically projected to a hyperplane and satisfy ''N''=3''n''/2+2. *Severi showed in 1901 that the only Severi variety with ''n''=2 is the Veronese surface in P5. *The only Severi variety with ''n''=4 is the Segre embedding of P2×P2 into P8, found by Scorza in 1908. *The only Segre variety with ''n''=8 is the 8-dimensional Grassmannian ''G''(1,5) of lines in ...

People From The Province Of Cosenza
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of p ...
