Enrico Giusti
Enrico Giusti (born Priverno, 1940), is an Italian mathematician mainly known for his contributions to the fields of calculus of variations, regularity theory of partial differential equations, minimal surfaces and history of mathematics. He has been professor of mathematics at the Università di Firenze; he also taught and conducted research at the Australian National University at Canberra, at the Stanford University and at the University of California, Berkeley. After retirement, he devoted himself to the managing of the "Giardino di Archimede", a museum entirely dedicated to mathematics and its applications. Giusti is also the editor-in-chief of the international journal, dedicated to the history of mathematics "Bollettino di storia delle scienze matematiche". One of the most famous results of Giusti, is the one obtained with Enrico Bombieri and Ennio De Giorgi, concerning the minimality of Simons' cones, and allowing to disprove the validity of Bernstein's theorem in dimens ...

Priverno
Priverno is a town, ''comune'' in the province of Latina, Lazio, central Italy. It was called ''Piperno'' until 1927. It has a station of the Rome-Naples railway mainline. Nearby is the Monti Lepini chain. It was the birthplace of the canonist Reginald of Piperno. History ''Privernum'' is described by Livy as a flourishing Volscian site, which was conquered and destroyed by the Romans in the late 4th century BC. The Appian Way passed nearby. The town recovered under the Roman rule, but disappeared after the fall of the Western Roman Empire, probably destroyed by Saracen attacks. It was later a minor center of the Papal States, to which it belonged until the capture of Rome in 1870. Main sights Nearby is the Abbey of Fossanova, which is where the town's patron saint, St. Thomas Aquinas died on 7 March 1274. Other churches include: *''Santa Maria Assunta'' (former Cathedral), consecrated by Pope Lucius II in 1183. It houses a panel of the ''Madonna d'Agosto'' and St. Tho ...

Unione Matematica Italiana
The Italian Mathematical Union ( it, Unione Matematica Italiana) is a mathematical society based in Italy. It was founded on December 7, 1922 by Luigi Bianchi, Vito Volterra, and most notably, Salvatore Pincherle, who became the Union's first President. History Salvatore Pincherle, professor at the University of Bologna, sent on 31 March 1922 a letter to all Italian mathematicians in which he planned the establishment of a national mathematical society. The creation was inspired by similar initiatives in other countries, such as the Société mathématique de France (1872), the Deutsche Mathematiker-Vereinigung (1891), the American Mathematical Society (1891) and, above all, the International Mathematical Union (1920). The most important italian mathematicians of the time - among all Luigi Bianchi and Vito Volterra - encouraged Pincherle's initiative also by personally sending articles for the future Bulletin; overall, about 180 mathematicians replied to Pincherle's letter.

Bologna
Bologna (, , ; egl, label= Emilian, Bulåggna ; lat, Bononia) is the capital and largest city of the Emilia-Romagna region in Northern Italy. It is the seventh most populous city in Italy with about 400,000 inhabitants and 150 different nationalities. Its metropolitan area is home to more than 1,000,000 people. It is known as the Fat City for its rich cuisine, and the Red City for its Spanish-style red tiled rooftops and, more recently, its leftist politics. It is also called the Learned City because it is home to the oldest university in the world. Originally Etruscan, the city has been an important urban center for centuries, first under the Etruscans (who called it ''Felsina''), then under the Celts as ''Bona'', later under the Romans (''Bonōnia''), then again in the Middle Ages, as a free municipality and later ''signoria'', when it was among the largest European cities by population. Famous for its towers, churches and lengthy porticoes, Bologna has a well-preserved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harnack's Inequality
In mathematics, Harnack's inequality is an inequality relating the values of a positive harmonic function at two points, introduced by . Harnack's inequality is used to prove Harnack's theorem about the convergence of sequences of harmonic functions. , and generalized Harnack's inequality to solutions of elliptic or parabolic partial differential equations. Such results can be used to show the interior regularity of weak solutions. Perelman's solution of the Poincaré conjecture uses a version of the Harnack inequality, found by , for the Ricci flow. The statement Harnack's inequality applies to a non-negative function ''f'' defined on a closed ball in R''n'' with radius ''R'' and centre ''x''0. It states that, if ''f'' is continuous on the closed ball and harmonic on its interior, then for every point ''x'' with , ''x'' − ''x''0, = ''r'' 0 (depending only on ''K'', \tau, t-\tau, and the coefficients of \mathcal) such that, for each t\in(\tau, ...

Bernstein Problem
In differential geometry, Bernstein's problem is as follows: if the graph of a function on R''n''−1 is a minimal surface in R''n'', does this imply that the function is linear? This is true in dimensions ''n'' at most 8, but false in dimensions ''n'' at least 9. The problem is named for Sergei Natanovich Bernstein Sergei Natanovich Bernstein (russian: Серге́й Ната́нович Бернште́йн, sometimes Romanized as ; 5 March 1880 – 26 October 1968) was a Ukrainian and Russian mathematician of Jewish origin known for contributions to parti ... who solved the case ''n'' = 3 in 1914. Statement Suppose that ''f'' is a function of ''n'' − 1 real variables. The graph of ''f'' is a surface in R''n'', and the condition that this is a minimal surface is that ''f'' satisfies the minimal surface equation :\sum_^ \frac\frac = 0 Bernstein's problem asks whether an ''entire'' function (a function defined throughout R''n''−1 ) t ...

Garden Of Archimedes
The Garden of Archimedes (Italian: ''Il Giardino Di Archimede'') is a museum for mathematics in Florence, Italy. It was founded on March 26, 2004 and opened its doors to the public on April 14 of that year. The mission of the museum is to enhance public understanding and perception of mathematics, to bring mathematics out of the shadows and into the limelight. It has been compared to the National Museum of Mathematics in New York City, the only museum in North America devoted to mathematics. History The Garden of Archimedes was set up in 2004 by a consortium of government and educational agencies. Current members of the consortium include: the Scuola Normale Superiore di Pisa, the University of Florence, the University of Pisa, the University of Siena, the Italian Mathematical Union, the Istituto Nazionale di Alta Matematica Francesco Severi, the Consortium for the Promotion of Culture of Research and Studies at the University of Avellino.
