The Tzitzeica equation is a nonlinear partial differential equation devised by Gheorghe Țițeica in 1907 in the study of differential geometry, describing surfaces of constant affine curvature.〔G. Tzitz´eica, “Geometric infinitesimale-sur une nouvelle classes de surfaces,”Comptes Rendus de l’Acad´emie des Sciences, vol. 144, pp. 1257–1259, 1907.〕 The Tzitzeica equation has also been used in nonlinear physics, being an integrable 1+1 dimensional Lorentz invariant system.〔Andrei D. Polyanin,Valentin F. Zaitsev, HANDBOOK OF NONLINEAR PARTIAL DIFFERENTIAL EQUATIONS, SECOND EDITION p540-542 CRC PRESS〕 On substituting : the equation becomes Obtain the traveling solution of the original equation by the reverse transformation . ==References== 〔 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「Tzitzeica equation」の詳細全文を読む スポンサード リンク
