Marc Edward Culler (born November 22, 1953) is an American mathematician who works in geometric group theory and low-dimensional topology. A native Californian, Culler did his undergraduate work at the University of California at Santa Barbara and his graduate work at Berkeley where he graduated in 1978. He is now at the University of Illinois at Chicago. Culler is the son of Glen Jacob Culler who was an important early innovator in the development of the Internet. ==Work== Culler specializes in group theory,〔(People in Geometric Group Theory )〕 low dimensional topology, 3-manifolds, and hyperbolic geometry. Culler frequently collaborates with Peter Shalen and they have co-authored many papers.〔Culler, Marc; Shalen, Peter B. Varieties of group representations and splittings of 3-manifolds. Ann. of Math. (2) 117 (1983), no. 1, 109–146.〕〔Culler, Marc; Gordon, C. McA.; Luecke, J.; Shalen, Peter B. Dehn surgery on knots. Ann. of Math. (2) 125 (1987), no. 2, 237–300〕 Culler and Shalen did joint work that related properties of representation varieties of hyperbolic 3-manifold groups to decompositions of 3-manifolds. In particular, Culler and Shalen used the Bass–Serre theory, applied to the function field of the SL(2,C)-Character variety of a 3-manifold, to obtain information about incompressible surfaces in the manifold. Based on this work, Shalen, Cameron Gordon, John Luecke, and Culler proved the cyclic surgery theorem. Another important contribution by Culler came in a 1986 paper with Karen Vogtmann called "Moduli of graphs and automorphisms of free groups". This paper introduced an object that came to be known as Culler–Vogtmann Outer space. Culler is one of the authors of a 1994 paper called "Plane curves associated to character varieties of 3-manifolds"〔D. Cooper, M. Culler, H. Gillet, D. D. Long and P. B. Shalen. Plane curves associated to character varieties of 3-manifolds. Invent. Math., 118(1):47--84, 1994.〕 which introduced the A-polynomial of a knot〔(The A-polynomial and the FFT ), in PDF format〕 or, more generally, of a 3-manifold with one torus boundary component. Culler is an editor of ''The New York Journal of Mathematics''.〔( New York Journal of Mathematics )〕 He was a Sloan Foundation Research Fellow〔(Sloan Research Fellowships )〕 (1986–1988) and a UIC University Scholar〔(UIC News: 2008 University Scholar Marc Culler )〕〔(UIC College awards )〕 (2008). In 2014, he became a Fellow of the American Mathematical Society.〔(List of Fellows of the American Mathematical Society )〕 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「Marc Culler」の詳細全文を読む スポンサード リンク
