He was born in Ithaca, New York, to parents Horace B. Davis and Marian R. Davis. In 1948 he married Natalie Zemon Davis; they have three children. His father was a member of the CPUSA. He moved to Canada in the early 1960s and began teaching at the University of Toronto. He has lived in Canada longer than he lived in the US. ==Mathematics== In 1950 he received a doctorate in mathematics from Harvard University. His principal research investigations involve linear algebra and operator theory in Hilbert space. Furthermore he has made contributions to numerical analysis, geometry, and algebraic logic. He is one of the eponyms of the Davis–Kahan theorem and Bhatia–Davis inequality (along with Rajendra Bhatia). The Davis-Kahan-Weinberger dilation theorem 〔(Chandler Davis, W. M. Kahan, and H. F. Weinberger Norm-Preserving Dilations and Their Applications to Optimal Error Bounds, SIAM J. Numer. Anal. 19-3 (1982), pp. 445-469. )〕 is one of the landmark results in the dilation theory of Hilbert space operators and has found applications in many different areas. A PhD thesis titled "Backward Perturbation and Sensitivity Analysis of Structured Polynomial Eigenvalue Problem" 〔(B. Adhikari, Backward Perturbation and Sensitivity Analysis of Structured Polynomial Eigenvalue Problems, Ph.D. thesis, Department of Mathematics, IIT Guwahati, Guwahati, India, 2008. )〕 is dedicated to this theorem. Davis has written around eighty research papers in mathematics. Davis was a professor in the mathematics department of University of Michigan, working alongside Wilfred Kaplan. He is currently one of the co-Editors-in-Chief of the ''Mathematical Intelligencer''. In 2012 he became a fellow of the American Mathematical Society.〔(List of Fellows of the American Mathematical Society ), retrieved 2012-11-10.〕 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「Chandler Davis」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.
