Daniel J. Kleitman (born October 4, 1934)〔(Kleitman, Daniel J in ''American Men of Science'', vol. 4, 2009 )〕 is a professor of applied mathematics at MIT. His research interests include combinatorics, graph theory, genomics, and operations research. == Biography == Kleitman was born in New York, New York in 1934. received his PhD in Physics from Harvard University in 1958 under Nobel Laureates Julian Schwinger and Roy Glauber. He is the "k" in G. W. Peck, a pseudonym for a group of six mathematicians that includes Kleitman. Formerly a physics professor at Brandeis University,〔 Kleitman was encouraged by Paul Erdős to change his field of study to mathematics. Perhaps humorously, Erdős once asked him, "Why are you ''only'' a physicist?"〔.〕 Kleitman joined the applied mathematics faculty at MIT in 1966, and was promoted to professor in 1969.〔(【引用サイトリンク】title=MIT Mathematics - Daniel Kleitman )〕 Kleitman coauthored at least six papers with Erdős, giving him an Erdős number of 1. He was a math advisor and extra for the film ''Good Will Hunting.''〔Daniel J. Kleitman, ("My Career in the Movies," ), ''Notices of the American Mathematical Society'', 45, 502 (April 1998)〕 Since Minnie Driver, who appeared in ''Good Will Hunting'', also appeared in ''Sleepers'' with Kevin Bacon, Kleitman has a Bacon number of 2. Adding the two numbers results in an Erdős–Bacon number of 3, tied for lowest currently. 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「Daniel Kleitman」の詳細全文を読む スポンサード リンク
