At the Corner of Space and Time
(University of Waterloo, 2019-12-09)We perform a rigorous piecewise-flat discretization of classical general relativity in the first-order formulation, in both 2+1 and 3+1 dimensions, carefully keeping track of curvature and torsion via holonomies. We show ... -
Canonical Structure and Conservation Laws of General Relativity on Null Surfaces and at Null Infinity
(University of Waterloo, 2021-01-12)The first part of this thesis addresses the canonical structure of general relativity on generic null surfaces. The pre-symplectic potential of metric general relativity, evaluated on a null surface, is decomposed into ...
