Ganea left Communist Romania to settle in the United States in the early 1960s. He taught at the University of Washington. ==Work== In 1957, Ganea published in the ''Annals of Mathematics'' a short, yet influential paper with Samuel Eilenberg, in which the Eilenberg–Ganea theorem was proved and the celebrated Eilenberg–Ganea conjecture was formulated. The conjecture is still open. Just before he died, Ganea attended the Symposium on Algebraic Topology, held February 22–26, 1971 at the Battelle Seattle Research Center, in Seattle. At the symposium, he was not able to give a talk, but he did distribute a preprint containing a list of unsolved problems. One of these problems, regarding the ''Lusternik–Schnirelmann category'', came to be known as ''Ganea's conjecture''. Many particular cases of this conjecture were proved, until Norio Iwase provided a counterexample in 1998. 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「Tudor Ganea」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.
