Onorato Nicoletti
Onorato Nicoletti (21 June 1872 – 31 December 1929) was an Italian mathematician. Biography Nicoletti received his ''laurea'' in 1894 from the Scuola Normale di Pisa. In 1898, he became a professor of infinitesimal calculus at the University of Modena. After two years, he returned to Pisa, where he was a teacher of algebra, and then, after the death of Ulisse Dini, of infinitesimal calculus. He published works in various fields of mathematics, including numerical analysis, infinitesimal analysis, the equations related to hermitian matrix, hermitian matrices, and differential equations. He made original contributions to Max Dehn's theory of the equivalence of polyhedra under polyhedral dissection and reassembly (scissors-congruent, scissors-congruence), extending and generalizing the theory with an entire class of new relations. Nicoletti collaborated in the writing of ''Enciclopedia Hoepli delle Matematiche elementari e complementi'' (published from 1930 to 1951) with the contr ...

Scuola Normale Di Pisa
The Scuola Normale Superiore (commonly known in Italy as "la Normale") is a public university in Pisa and Florence, Tuscany, Italy, currently attended by about 600 undergraduate and postgraduate (PhD) students. Together with the University of Pisa and Sant'Anna School of Advanced Studies, it is part of the Pisa University System. It was founded in 1810 with a decree by Napoleon as a branch of the École normale supérieure in Paris, with the aim of training the teachers of the Empire to educate its citizens. In 2013 the Florentine site was added to the historical site in Pisa, following the inclusion of the Institute of Human Sciences in Florence (SUM). Since 2018 the Scuola Normale Superiore has been federated with the Sant'Anna School of Advanced Studies in Pisa, with the Institute for Advanced Studies of Pavia, and the Scuola Superiore Meridionale of Naples the only other three university institutions with special status that, in the Italian panorama, offer, in accordance wi ...

University Of Modena
The University of Modena and Reggio Emilia (), located in Modena and Reggio Emilia, Emilia-Romagna, Italy, is one of the oldest universities in Europe, founded in 1175, with a population of 20,000 students. The medieval university disappeared by 1338 and was replaced by "three public lectureships" which did not award degrees and were suspended in the 1590s "for lack of money". The university was not reestablished in Modena until the 1680s and did not receive an imperial charter until 1685.Quoted from: Grenler, Paul F. The Universities of the Italian Renaissance Johns Hopkins University Press, 2004. Page 137. Some famous students who attended the university include Ludovico Antonio Muratori, a noted Italian historian and scholar who graduated in 1694, the playwright Carlo Goldoni in the 17th century and, in the last century, Sandro Pertini, who became President of the Italian Republic.

Ulisse Dini
Ulisse Dini (14 November 1845 – 28 October 1918) was an Italian mathematician and politician, born in Pisa. He is known for his contributions to real analysis, partly collected in his book "''Fondamenti per la teorica delle funzioni di variabili reali''". Life and academic career Dini attended the Scuola Normale Superiore in order to become a teacher. One of his professors was Enrico Betti. In 1865, a scholarship enabled him to visit Paris, where he studied under Charles Hermite as well as Joseph Bertrand, and published several papers. In 1866, he was appointed to the University of Pisa, where he taught algebra and geodesy. In 1871, he succeeded Betti as professor for Mathematical analysis, analysis and geometry. From 1888 until 1890, Dini was ''rettore'' of the Pisa University, and of the ''Scuola Normale Superiore'' from 1908 until his death in 1918. He was also active as a politician: in 1871 he was voted into the Pisa city council and in 1880 became a member of the Parlia ...

Hermitian Matrix
In mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose—that is, the element in the -th row and -th column is equal to the complex conjugate of the element in the -th row and -th column, for all indices and : A \text \quad \iff \quad a_ = \overline or in matrix form: A \text \quad \iff \quad A = \overline . Hermitian matrices can be understood as the complex extension of real symmetric matrices. If the conjugate transpose of a matrix A is denoted by A^\mathsf, then the Hermitian property can be written concisely as A \text \quad \iff \quad A = A^\mathsf Hermitian matrices are named after Charles Hermite, who demonstrated in 1855 that matrices of this form share a property with real symmetric matrices of always having real eigenvalues. Other, equivalent notations in common use are A^\mathsf = A^\dagger = A^\ast, although in quantum mechanics, A^\ast typically means the complex conjugate onl ...

Max Dehn
Max Wilhelm Dehn (November 13, 1878 – June 27, 1952) was a German mathematician most famous for his work in geometry, topology and geometric group theory. Dehn's early life and career took place in Germany. However, he was forced to retire in 1935 and eventually fled Germany in 1939 and emigrated to the United States.The story of his travel in 1940 from Norway via Stockholm, Moscow, trans-Siberian train, Vladivostok, Japan to San Francisco is described in Dehn was a student of David Hilbert, and in his habilitation in 1900 Dehn resolved Hilbert's third problem, making him the first to resolve one of Hilbert's problems, Hilbert's well-known 23 problems. Dehn's doctoral students include Ott-Heinrich Keller, Ruth Moufang, and Wilhelm Magnus; he also mentored mathematician Peter Nemenyi and the artists Dorothea Rockburne and Ruth Asawa. Biography Dehn was born to a family of Jewish origin in Hamburg, Imperial Germany. He studied the foundations of geometry with David Hilbert, Hil ...

Scissors-congruent
The third of Hilbert's problems, Hilbert's list of mathematical problems, presented in 1900, was the first to be solved. The problem is related to the following question: given any two polyhedron, polyhedra of equal volume, is it always possible to cut the first into finitely many polyhedral pieces which can be reassembled to yield the second? Based on earlier writings by Carl Friedrich Gauss, David Hilbert conjectured that this is not always possible. This was confirmed within the year by his student Max Dehn, who proved that the answer in general is "no" by producing a counterexample. The answer for the analogous question about polygons in 2 dimensions is "yes" and had been known for a long time; this is the Wallace–Bolyai–Gerwien theorem. Unknown to Hilbert and Dehn, Hilbert's third problem was also proposed independently by Władysław Kretkowski for a math contest of 1882 by the Academy of Arts and Sciences of Kraków, and was solved by Ludwik Birkenmajer, Ludwik Antoni B ...

Roberto Marcolongo
Roberto Marcolongo (August 28, 1862 in Rome – May 16, 1943 in Rome) was an Italian mathematician, known for his research in vector calculus and theoretical physics. Biography Marcolongo graduated in 1886, and later he was an assistant of Valentino Cerruti in Rome. In 1895 he became professor of rational mechanics at the University of Messina. In 1908 he moved to the University of Naples, where he remained until retirement in 1935. He worked on vector calculus together with Cesare Burali-Forti, which was then known as "Italian notation". In 1906 he wrote an early work which used the four-dimensional formalism to account for relativistic invariance under Lorentz transformations. In 1921 he published to Messina one of the first treaties on the special relativity and general, where he used the absolute differential calculus without coordinates, developed with Burali-Forti, as opposed to the absolute differential calculus with coordinates of Tullio Levi-Civita and Gregorio Ricci- ...
