William Thurston
William Paul Thurston (born October 30, 1946 in Washington, DC - † August 21, 2012 in Rochester , New York ) - commonly known as Bill Thurston - was an American mathematician .
He came up with the idea of geometrizing to classify closed three-dimensional manifolds . For this he received the Fields Medal in 1982 . His theories linked mathematical areas previously viewed as separate with the theory of three-dimensional manifolds.
Life
Thurston studied at New College in Sarasota in Florida ( Bachelor's degree in 1967) and then at Morris Hirsch and Stephen Smale at the University of Berkeley , where he received his doctorate in 1972 with a thesis on foliations special 3-manifolds (Foliations of 3-manifolds Which are circle bundles ) . In 1972/73 he was at the Institute for Advanced Study in Princeton . In 1973 he became an Assistant Professor at the Massachusetts Institute of Technology (MIT) and in 1974 Professor of Mathematics at Princeton University . Since 1991 he has been a professor at UC Berkeley , since 1996 at UC Davis and from 2003 at Cornell University . He was also director of the MSRI from 1992–97 .
In his laudatory speech on the awarding of the Fields Medal to Thurston in 1982, CTC Wall emphasized that Thurston revolutionized the field of topology of two- and three-dimensional manifolds with "fantastic geometric intuition and vision". In particular, Thurston clarified the central role of hyperbolic manifolds (that is, manifolds with a metric of constant negative curvature) also in the three-dimensional case (see geometrization of 3-manifolds ). In his geometrization conjecture (which he proved for the special case of hook manifolds) he classified three-dimensional manifolds into eight types. Previously, the classifications in dimensions two and greater than five were well understood, but not in dimensions three and four. The proof of the geometrization conjecture of Thurston (with the Poincaré conjecture as part) succeeded Grigori Perelman in 2003. The theory of discrete groups of isometries of hyperbolic space ( Klein's groups ), which was previously largely isolated from the topology , thus became a central topic of three-dimensional topology .
Before that, he also revolutionized the theory of scrolls in the early 1970s .
In 1982 Thurston formulated a series of 24 conjectures about 3-manifolds, all but one of which have now been solved. In addition to the geometrization conjecture, it has long been an open problem whether hyperbolic 3-manifolds are virtually fiberized ; this was proven in 2013 by Ian Agol and Daniel Wise . It is still open (2016): Show that there are two hyperbolic 3-manifolds whose volumes are not in a rational relationship to one another.
He pursued an intuitive, initially not uncontroversial approach to mathematical knowledge with the aim of understanding mathematical structures with an emphasis on ideas rather than details of formal evidence (which he underlined in an article in the Bulletin of the AMS 1994). According to his pupil Benson Farb , Thurston fundamentally changed the approach of modern topologists and geometers to mathematical objects, in contrast to which the previously used method seemed more like the pure manipulation of symbols. He also developed a Geometry and the Imagination course to make advanced geometric concepts accessible to mathematically inexperienced people such as artists and designers. He also worked with the Japanese fashion designer Dai Fujiwara on the best representation of three-dimensional "manifolds" in two dimensions (clothes).
Thurston was married twice, in his first marriage to Rachel Findley he had three children (including the mathematicians Dylan and Nathaniel Thurston), in his second marriage to Julian Thurston he had two children.
