After that, he began studying mathematics at the University of Berlin under Leopold Kronecker, Lazarus Fuchs, and Wilhelm Dilthey. As he advanced in his studies, Lie groups became the focus of his interest. Since this area was poorly represented at Berlin, he moved to the University of Halle, where he obtained his doctorate in 1892 under Albert Wangerin with a dissertation on the topic ''Ueber eine gewisse Klasse continuirlicher Gruppen und ihren Zusammenhang mit den Additionstheoremen'' ("On a certain class of continuous groups and their relation to addition theorems"). After that, he worked at the Meteorological Institute of Berlin, where presumably his interest in applied mathematics developed. At the invitation of Felix Klein, he moved to the University of Göttingen, where he habilitated in 1894. In 1895, he was involved in starting a seminar on actuarial science at Göttingen. However, since he held no permanent position there, he went to Berlin in 1903 to work as the Chief Actuary for the German subsidiary of the New York Mutual Life Insurance Company. In 1901, he wrote the entry on life insurance mathematics in the ''Enzyklopädie der mathematischen Wissenschaften'' ("Encyclopaedia of Mathematical Sciences") in which he gave axioms for probability theory long before Andrey Kolmogorov did so in 1933. In particular, he was the first to give the modern definition of statistical independence. Compared to the current structure of probability theory, his work only lacked the technical condition of sigma additivity. However, in contrast to Kolmogorov, Bohlmann failed to prove significant theorems within his axiomatic framework. As a result, his fundamental contributions to probability theory gained very little attention. In particular, though Kolmogorov had visited Göttingen several times in the late 1920s, he had no knowledge of Bohlmann's work. 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「Georg Bohlmann」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.
