Paul Erdős has been his academic influence and inspiration ever since he was 14. ==Early life and education== As a student, he took part in the first three International Mathematical Olympiads, winning two gold medals. Paul Erdős invited Bollobás to a lunch after hearing about his accomplishment and they kept in touch since then. His first publication was a joint publication with Erdős on extremal problems in graph theory that was written when he was in high school in 1962. With Erdős’s recommendation to Harold Davenport and Bollobás’s long campaigning to get permission from the Communist authorities, Bollobás was able to spend a year in Cambridge, England, during his undergraduate studies. However, his return to Cambridge again to complete his Ph.D. upon an offer from the university was denied by the Communist authorities. A following scholarship offer from Paris was also rejected by the authorities. He wrote his first doctorate in discrete geometry under the supervision of László Fejes Tóth and Paul Erdős in Budapest University, 1967, after which he spent a year in Moscow with Israïl Moiseevich Gelfand. After spending a year at Christ Church, Oxford, where Michael Atiyah held the Savilian Chair of Geometry, and vowing never to return to Hungary due to his disillusion with the 1956 Soviet intervention and subsequent puppet communist regime, he went to Trinity College, Cambridge, where in 1972 he received a second Ph.D. in functional analysis (on Banach algebras) under the supervision of Frank Adams.〔 In 1970, he was awarded a fellowship to the college. His main area of research was combinatorics, particularly in graph theory. The two areas that interest him most are extremal graph theory and random graph theory. Bollobás stayed in Cambridge from 1971 to 1996. 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「Béla Bollobás」の詳細全文を読む スポンサード リンク
