Alberto Tognoli
Alberto Tognoli (born 26 July 1937, Brescia, died 3 March 2008 in Rapallo) was an Italian mathematician, who worked on algebraic geometry. Tognoli received his Ph.D. (Laurea) in 1960 from the University of Pisa. From 1970 he became full professor at the same university, and he also taught in Cosenza, Ferrara, Paris and Tours. He was also a professor of geometry at the University of Trento from 1986 until his retirement as professor emeritus in 2005. He is known for his research on Nash functions and Nash manifolds (named after John Nash). He proved Nash's conjecture that smooth compact manifolds are diffeomorphic to non-singular real algebraic manifolds (known as the Theorem of Nash and Tognoli). He received in 1974 the Caccioppoli Prize The Caccioppoli Prize is awarded by the Italian Mathematical Union to an Italian mathematician not exceeding the age of 38 who established a wide international reputation.

Rapallo
Rapallo ( , , ) is a municipality in the Metropolitan City of Genoa, located in the Liguria region of northern Italy. As of 2017 it had 29,778 inhabitants. It lies on the Ligurian Sea coast, on the Tigullio Gulf, between Portofino and Chiavari, 25 kilometers east-south east of Genoa itself. The climate is moderate. Many of the villas are built in the hills that rise immediately behind the city, protecting them from strong northern winds. The Parco Naturale Regionale di Portofino, encompassing the territory of six Ligurian communes, includes the Rapallo area. History The first settlement dates probably from the 8th century BC, although the findings have not clarified if it was Etruscan or Greek. The name of the city appears for the first time in a document from 964. In 1203 the ''Podestà'' of Rapallo was created, and the town became a Genoese dominion in 1229, remaining under that aegis until the Napoleonic Wars. Galleys from Rapallo took part to the Battle of Meloria of 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Trento
The University of Trento (Italian: ''Università degli Studi di Trento'') is an Italian university located in Trento and nearby Rovereto. It has been able to achieve considerable results in didactics, research, and international relations according to CENSIS ( Centro Studi Investimenti Sociali ) and the Italian Ministry of Education. History The University of Trento was founded in 1962 as a Higher University Institute for Social Sciences. It then became the first Faculty of Sociology in Italy. The impact on the city was quite contradictory: the university was seen both as a motivating force for cultural openness and the creation of a new leading class, but also as a fracturing element of protest. In order to expand the educational opportunities of the University of Trento, in 1972 the Faculty of Science was founded and in 1973 so was the Faculty of Economics. The academic project was expanded in 1984 with the Faculties of Arts and Humanities and Law and in 1985 with the Faculty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nash Function
In real algebraic geometry, a Nash function on an open semialgebraic subset ''U'' ⊂ R''n'' is an analytic function ''f'': ''U'' → R satisfying a nontrivial polynomial equation ''P''(''x'',''f''(''x'')) = 0 for all ''x'' in ''U'' (A semialgebraic subset of R''n'' is a subset obtained from subsets of the form or , where ''P'' is a polynomial, by taking finite unions, finite intersections and complements). Some examples of Nash functions: *Polynomial and regular rational functions are Nash functions. *x\mapsto \sqrt is Nash on R. *the function which associates to a real symmetric matrix its ''i''-th eigenvalue (in increasing order) is Nash on the open subset of symmetric matrices with no multiple eigenvalue. Nash functions are those functions needed in order to have an implicit function theorem in real algebraic geometry. Nash manifolds Along with Nash functions one defines Nash manifolds, which are semialgebraic analytic submanifolds of some R''n''. A Nash mapping between Na ...

John Forbes Nash, Jr
John Forbes Nash Jr. (June 13, 1928 – May 23, 2015) was an American mathematician who made fundamental contributions to game theory, real algebraic geometry, differential geometry, and partial differential equations. Nash and fellow game theorists John Harsanyi and Reinhard Selten were awarded the 1994 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel (popularly known as the Nobel Prize in Economics). In 2015, he and Louis Nirenberg were awarded the Abel Prize for their contributions to the field of partial differential equations. As a graduate student in the Mathematics Department at Princeton University, Nash introduced a number of concepts (including Nash equilibrium and the Nash bargaining solution) which are now considered central to game theory and its applications in various sciences. In the 1950s, Nash discovered and proved the Nash embedding theorems by solving a system of nonlinear partial differential equations arising in Riemannian geome ...

University Of Pisa Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in ...
