Conformally flat pseudo Riemannian Homogeneous Ricci Solitons 4 spaces
Mohamad Chaichi, Yadollah Keshavarzi
We consider four dimensional conformally flat homogeneous pseudo Riemannian manifolds. According to forms (Seger types) of the Ricci operator, we provide a full classification of f…

On Lorentzian two-symmetric manifolds of dimension four
A. Zaeim, M. Chaichi, Y. Aryanejad
We study curvature properties of four-dimensional Lorentzian manifold with two-symmetry property. We then consider Einstein-like metrics, Ricci solitons and homogeneity over these…
