Attilio Palatini (18 November 1889 – 24 August 1949) was an Italian mathematician born in Treviso.〔 (An Italian short biography of Attilio Palatini ) in ''Edizione Nazionale Mathematica Italiana online''.〕〔Rocco Serini, ''Necrologio di Attilio Palatini'', Bollettino dell’Unione Matematica Italiana, serie 3, volume 4 (1949), n. 3, pp. 334-335.〕 ==Biography== He graduated in mathematics in 1913 at the University of Padua, where he was a student of Ricci-Curbastro and of Levi-Civita. He taught rational mechanics at the Universities of Messina, Parma and Pavia. He was mainly involved in absolute differential calculus and in general relativity. Within this latter subject he gave a sound generalization of the variational principle. In 1919, Palatini wrote an important article where he proposed a new approach to the variational formulation of Einstein's gravitational field equations.〔A. Palatini (1919) ''Deduzione invariantiva delle equazioni gravitazionali dal principio di Hamilton'', Rend. Circ. Mat. Palermo ''43'', 203-212 (translation by R.Hojman and C. Mukku in P.G. Bergmann and V. De Sabbata (eds.) Cosmology and Gravitation, Plenum Press, New York (1980) )〕 In the same paper, Palatini also showed that the variations of Christoffel symbols constitute the coordinate components of a tensor. He wrote the "Rational Mechanics" and "Theory of relativity" entries for the ''Hoepli Encyclopedia of Elementary mathematics''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Attilio Palatini」の詳細全文を読む スポンサード リンク
