Lorentzian spacetimes with constant curvature invariants in three dimensions
Alan Coley, Sigbjorn Hervik, Nicos Pelavas
In this paper we study Lorentzian spacetimes for which all polynomial scalar invariants constructed from the Riemann tensor and its covariant derivatives are constant (CSI spacetim…
Classification of the Weyl Tensor in Higher Dimensions and Applications
A. Coley
We review the theory of alignment in Lorentzian geometry and apply it to the algebraic classification of the Weyl tensor in higher dimensions. This classification reduces to the th…
Late-time behaviour of the tilted Bianchi type VI models
S Hervik, R J van den Hoogen, W C Lim +1
We study tilted perfect fluid cosmological models with a constant equation of state parameter in spatially homogeneous models of Bianchi type VI using dynamical systems me…
Averaging and Cosmological Observations
A. A. Coley
The gravitational field equations on cosmological scales are obtained by averaging the Einstein field equations of general relativity. By assuming spatial homogeneity and isotropy…
Late-time behaviour of the tilted Bianchi type VIh models
S Hervik, R J van den Hoogen, W C Lim +1
We study tilted perfect fluid cosmological models with a constant equation of state parameter in spatially homogeneous models of Bianchi type VI_h using dynamical systems methods a…
