Collineations of the Ricci tensor

Journal of Mathematical Physics, 1993
Ricci collineations for the Ricci tensor which is constructed from a general spherically symmetric and static metric are classified for all possibilities of Rab(r) (such that Rab≠0 for a=b). It turns out that the only collineations admitted by this tensor can be ten, six, or four and there does not appear any case in between.

Warped Product Metrics with Rank-1 Ricci Tensor

EAS Publications Series, 2008
Locally 2+2 warped product metrics with a Lorentzian base and Riemannian fiber are described in Newman-Penrose formalism. It is shown that solutions with rank-1 Ricci tensor are characterized by Φ 11 + 3Λ = 0 and Φ 00 Φ 22 = (Φ 11 -3Λ) 2 .

On Hermitian surfaces with J -invariant Ricci tensor

Journal of Geometry, 2001
Let \(M(J,g)\) be a compact Hermitian surface. Let \(s\) denote the usual scalar curvature of \(M(J,g)\), and \(k\) its conformal scalar curvature. By definition, \(k\) is the scalar curvature with respect to \(g\) of the canonical Weyl structure associated to the Hermitian structure \((J,g)\).
