Primeval symmetries
(Springer, 2007-11-01)
A detailed examination of the Killing equations in Robertson-Walker coordinates shows how the addition of matter and/or radiation to a de Sitter Universe breaks the symmetry generated by four of its Killing fields. The ...

Affine Killing vector fields on homogeneous surfaces with torsion
(IOP Publishing, 2019-06)
Many extensions of General Relativity are based on considering metric and affine structures as independent properties of spacetime. This leads to the possibility of introducing torsion as an independent degree ...

Conformal Killing Vector Fields and Rellich Type Identities on Riemannian Manifolds, II

Periodic geodesics and geometry of compact Lorentzian manifolds with a Killing vector field
(SPRINGER, 2011)
We study the geometry and the periodic geodesics of a compact Lorentzian manifold that has a Killing vector field which is timelike somewhere. Using a compactness argument for subgroups of the isometry group, we prove the ...
Bifundamental fuzzy 2-Sphere and fuzzy killing spinors
(2010-12-01)
We review our construction of a bifundamental version of the fuzzy 2-sphere and its relation to fuzzy Killing spinors, first obtained in the context of the ABJM membrane model. This is shown to be completely equivalent to ...
