In any physical theory, it is important to understand when solutions to the fundamental field equation exist, and answering this question has been the central theme of York's scientific work, culminating in the achievement, with Yvonne Choquet-Bruhat, of formulating the Einstein field equation as a well-posed system in the sense of the theory of partial differential equations.
Yvonne Choquet-Bruhat has two daughters and a son, Daniel Choquet.
