Discrete gravity as a topological field theory with light-like curvature defects
Wolfgang Wieland
I present a model of discrete gravity, which is formulated in terms of a topological gauge theory with defects. The theory has no local degrees of freedom and the gravitational fie…

Quasi-local gravitational angular momentum and centre of mass from generalised Witten equations
Wolfgang Wieland
Witten's proof for the positivity of the ADM mass gives a definition of energy in terms of three-surface spinors. In this paper, we give a generalisation for the remaining six Poin…
