He received his Ph.D. from the University of Berlin in 1899 under the guidance of Hermann Schwarz and Lazarus Fuchs. His name is usually associated with projective geometry, where he is known for proving that Desargues' theorem is a consequence of Pappus's hexagon theorem,〔("Hessenberg's Work in Projective Geometry" ) at www.cirm.univ-mrs.fr〕 and differential geometry where he is known for introducing the concept of a connection.〔 . 〕〔(Hessenberg, Gerhard (1874-1925) ) from Eric Weisstein's World of Scientific Biography〕 He was also a set theorist: the Hessenberg sum and product of ordinals are named after him. However, Hessenberg matrices are named for Karl Hessenberg, a near relative. ==Publications== * * (also in book form as a separate publication from Verlag Vandenhoeck und Ruprecht, Göttingen 1906). * * (unaltered reprint of the Teubner edition of 1912). * 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「Gerhard Hessenberg」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
