Almost conformal Ricci solitons on \(f\)-Kenmotsu manifolds
2019Summary: The object of the present paper is to study the \(\phi\)-Ricci symmetric, locally \(\phi\)-Ricci symmetric and cyclic Ricci parallel three-dimensional \(f\)-Kenmotsu manifold bearing the function \(f\) being constant. We have considered almost conformal Ricci soliton on the three-dimensional \(f\)-Kenmostu manifold and deduced the condition ...

On gradient Ricci solitons conformal to a pseudo-Euclidean space
Israel Journal of Mathematics, 2014The article under review is devoted to particular gradient Ricci solitons. By definition, a semi-Riemannian manifold \((M^n, g)\), \(n\geq 3\), is called a gradient Ricci soliton, if there exists a smooth function \(f:M^n\to \mathbb R\), called a potential function, such that \[ \mathrm{Ric}_g + \mathrm{Hess}_g (f) = \rho g, \] where \(\mathrm{Ric}_g\)

Geometry of almost conformal Ricci solitons on weakly Ricci symmetric spacetime
Reviews in Mathematical PhysicsThe aim of this paper is to study geometrical aspects of the almost conformal Ricci solitons on weakly Ricci symmetric perfect fluid spacetime obeying Einstein field equations. Among others, we first find the soliton constant and cosmological constant in weakly Ricci symmetric spacetime.

Conformal η-Ricci–Bourguignon soliton in general relativistic spacetime
International Journal of Geometric Methods in Modern PhysicsIn this research paper, we determine the nature of conformal [Formula: see text]-Ricci–Bourguignon soliton on a general relativistic spacetime with torse forming potential vector field. Besides this, we evaluate a specific situation of the soliton when the spacetime admitting semi-symmetric energy–momentum tensor with respect to conformal [Formula ...
