New positive small vacuum region gravitational energy expressions
Published 16 Jan 2009 in gr-qc | (0901.2400v1)
Abstract: We construct an infinite number of new holonomic quasi-local gravitational energy-momentum density pseudotensors with good limits asymptotically and in small regions, both materially and in vacuum. For small vacuum regions they are all a positive multiple of the Bel-Robinson tensor and consequently have positive energy.
