Curved spacetimes from quantum mechanics
László B. Szabados
The ultimate extension of Penrose's Spin Geometry Theorem is given. It is shown how the \emph{local} geometry of any \emph{curved} Lorentzian 4-manifold (with metric) can be…
Minkowski space from quantum mechanics
László B. Szabados
Penrose's Spin Geometry Theorem is extended further, from and (Euclidean) to (Poincaré) invariant elementary quantum mechanical systems. The Lorentzian spat…
A comment on Liu and Yau's positive quasi-local mass
N. O'Murchadha, L. B. Szabados, K. P. Tod
With the aid of a simple family of examples, we show that the quasi-local mass defined by Kijowski and Liu and Yau, and shown by Liu and Yau to be positive, may be strictly positiv…
The kernel of the edth operators on higher-genus spacelike two-surfaces
J. Frauendiener, L. B. Szabados
The dimension of the kernels of the edth and edth-prime operators on closed, orientable spacelike 2-surfaces with arbitrary genus is calculated, and some of its mathematical and ph…
Two dimensional Sen connections and quasi-local energy-momentum
L. B. Szabados
The recently constructed two dimensional Sen connection is applied in the problem of quasi-local energy-momentum in general relativity. First it is shown that, because of one of th…
