About Gregorio Ricci-Curbastro
Gregorio Ricci-Curbastro (Italian: [ɡreˈɡɔːrjo ˈrittʃi kurˈbastro]; 12 January 1853 – 6 August 1925) was an Italian mathematician. He is most famous as the discoverer of tensor calculus. With his former student Tullio Levi-Civita, he wrote his most famous single publication, a pioneering work on the calculus of tensors, signing it as Gregorio Ricci. This appears to be the only time that Ricci-Curbastro used the shortened form of his name in a publication, and continues to cause confusion. Ricci-Curbastro also published important works in other fields, including a book on higher algebra and infinitesimal analysis, and papers on the theory of real numbers, an area in which he extended the research begun by Richard Dedekind. == Early life and education == Completing his high school studies privately at only 16 years of age, he enrolled on the course of philosophy-mathematics at Rome University (1869). The following year, the Papal State fell, and so Gregorio was called by his father to the city of his birth, Lugo di Romagna. Subsequently, he attended courses at University of Bologna during the year 1872 - 1873, then transferred to the Scuola Normale Superiore di Pisa. In 1875, he graduated in Pisa in physical sciences and mathematics with a thesis on differential equations, entitled "On Fuchs's Research Concerning Linear Differential Equations". During his various travels, he was a student of the mathematicians Enrico Betti, Eugenio Beltrami, Ulisse Dini and Felix Klein.
