James W. York

from Wikipedia, the free encyclopedia

James Wesley York, Jr. (born July 3, 1939 in Raleigh , North Carolina ) is an American theoretical physicist who deals with gravitational theory.

York studied at North Carolina State University , where he received his bachelor's degree in 1962 and his doctorate in 1966. After teaching from 1968 at Princeton University , he went back to North Carolina State University in 1973 as a professor of physics. He became Agnew Hunter Bahnson Jr. Distinguished Professor of Physics in 1989 and Inter-Institutional Distinguished Professor of Physics in 2001 . After his retirement in 2002, he went to Cornell University as an honorary professor of astronomy and physics.

He examined u. a. the initial value problem in general relativity , for which he and Yvonne Choquet-Bruhat received the Dannie Heineman Prize for Mathematical Physics in 2003 . He was the first to emphasize the importance of conformal geometry in the initial value problem of general relativity and introduced concepts such as "York curvature" and "York time". He is currently working on an extension to initial value-boundary value problems for the gravitational field equations with the aim of numerical implementations.

In 2003 he received the Marcel Grossmann Award .
