A first-principles derivation of York scaling and the Lichnerowicz-York equation
Edward Anderson, Julian Barbour, Brendan Z. Foster +2
The only efficient and robust method of generating consistent initial data in general relativity is the conformal technique initiated by Lichnerowicz and perfected by York. In the…

Classical and Quantum Gravity on Conformal Superspace
Julian Barbour, Niall O Murchadha
The four-dimensional gauge group of general relativity corresponds to arbitrary coordinate transformations on a four-manifold. Theories of gravity with a dynamical structure remark…

Extremal variety as the foundation of a cosmological quantum theory
Julian Barbour, Lee Smolin
Dynamical systems of a new kind are described, which are motivated by the problem of constructing diffeomorphism invariant quantum theories. These are based on the extremization of…
