First-order action and Euclidean quantum gravity
Tomas Liko, David Sloan
We show that the on-shell path integral for asymptotically flat Euclidean spacetimes can be given in the first-order formulation of general relativity, without assuming the boundar…

Action and Hamiltonians in higher dimensional general relativity: First order framework
Abhay Ashtekar, David Sloan
We consider -dimensional space-times which are asymptotically flat at spatial infinity and show that, in the first order framework, the action principle is well-defined \emph{…

Asymptotics and Hamiltonians in a First order formalism
Abhay Ashtekar, Jonathan Engle, David Sloan
We consider 4-dimensional space-times which are asymptotically flat at spatial infinity and show that, in the first order framework, action principle for general relativity is well…
