Bochner Flatness and Soliton Dynamics in Lorentzian Kähler Spacetime Geometry
Karthika Ramasamya, Lavanya Kumara, Soumendu Roy +1
We study Riemann solitons and -hyperbolic Ricci solitons on Bochner-flat Lorentzian Kähler spacetime manifolds. Under the Einstein field equations with cosmological constant and…
Generalized Quasi Yamabe Gradient Solitons and Applications
Sinem Güler, Bülent Ünal
The purpose of this article is to study generalized quasi Yamabe gradient solitons on warped product manifolds. First, we obtain some necessary and sufficient conditions for the ex…
Killing Vector Fields of Standard Static Space-times
Fernando Dobarro, Bulent Unal
We consider Killing vector fields on standard static space-times and obtain equations for a vector field on a standard static space-time to be Killing. We also provide a characteri…
Hessian Tensor and Standard Static Space-times
Fernando Dobarro, Bulent Unal
In this brief survey, we will remark the interaction among the Hessian tensor on a semi-Riemannian manifold and some of the several questions in Lorentzian (and also in semi-Rieman…
Special Standard Static Space-Times
Fernando Dobarro, Bulent Unal
Essentially, some conditions for the Riemannian factor and the warping function of a standard static space-time are obtained in order to guarantee that no nontrivial warping functi…
Curvature of Multiply Warped Products
Fernando Dobarro, Bulent Unal
In this paper, we study Ricci-flat and Einstein Lorentzian multiply warped products. We also consider the case of having constant scalar curvatures for this class of warped product…
