Conformally Kähler Ricci solitons and base metrics for warped product Ricci solitons [PDF]

Pacific Journal of Mathematics, 2017
We investigate K hler metrics conformal to gradient Ricci solitons, and base metrics of warped product gradient Ricci solitons. The latter we name quasi-solitons. A main assumption that is employed is functional dependence of the soliton potential, with the conformal factor in the first case, and with the warping function in the second.

f– Kenmotsu Metric as Conformal Ricci Soliton

Annals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper, we study conformal Ricci solitons in f- Kenmotsu manifolds. We derive conditions for f-Kenmotsu metric to be a conformal Ricci soliton.

Ricci solitons on almost Kenmotsu 3-manifolds

Open Mathematics, 2017
Let (M3, g) be an almost Kenmotsu 3-manifold such that the Reeb vector field is an eigenvector field of the Ricci operator. In this paper, we prove that if g represents a Ricci soliton whose potential vector field is orthogonal to the Reeb vector field ...

Symmetries of f−associated standard static spacetimes and applications

Journal of the Egyptian Mathematical Society, 2017
The purpose of this note is to study and explore some collineation vector fields on standard static spacetimes If × M(also called f− associated SSST). Conformal vector fields, Ricci and matter collineations are studied.
