Study of η-Ricci–Yamabe Solitons and Ricci–Yamabe solitons in a Lorentzian Nearly Kähler Space-Time Manifold

Journal of Mathematics
An η-Ricci–Yamabe solitons is a notion of both Ricci and Yamabe solitons, defined by a geometric equation involving a tensor field, which has applications in general relativity and cosmology.

Conformally Flat Siklos Metrics Are Ricci Solitons

Axioms, 2020
We study and solve the Ricci soliton equation for an arbitrary locally conformally flat Siklos metric, proving that such spacetimes are always Ricci solitons.

h-Almost Ricci–Yamabe Solitons in Paracontact Geometry

Mathematics, 2022
In this article, we classify h-almost Ricci–Yamabe solitons in paracontact geometry. In particular, we characterize para-Kenmotsu manifolds satisfying h-almost Ricci–Yamabe solitons and 3-dimensional para-Kenmotsu manifolds obeying h-almost gradient ...

LP-Kenmotsu Manifolds Admitting η-Ricci Solitons and Spacetime

Journal of Mathematics, 2022
In the present paper, LP-Kenmotsu manifolds admitting η-Ricci solitons have been studied. Moreover, some results for η-Ricci solitons in LP-Kenmotsu manifolds in the spacetime of general relativity have also been proved.

Some geometrical properties of 4D homogeneous pseudo-Riemannian space with trivial isotropy [PDF]

ریاضی و جامعه, 2022
In this paper, we first consider $4D$ conformally flat homogeneous pseudo-Riemannian space with trivial isotropy, then, we investigate some geometrical properties such as being Ricci solitons and Walker on the spaces under consideration.

Generalized Sasakian Space-Forms with Beta-Kenmotsu Structure and Ricci Solitons [PDF]

International Journal of Mathematical, Engineering and Management Sciences
We explore the properties of almost Ricci solitons and the gradient Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure. We consider almost Ricci solitons on generalized Sasakian-space-forms with beta-Kenmotsu structure when ...

A study on conformal Ricci solitons and conformal Ricci almost solitons within the framework of almost contact geometry

Karpatsʹkì Matematičnì Publìkacìï, 2023
The goal of this paper is to find some important Einstein manifolds using conformal Ricci solitons and conformal Ricci almost solitons. We prove that a Kenmotsu metric as a conformal Ricci soliton is Einstein if it is an $\eta$-Einstein or the potential ...

Sasakian Manifolds Admitting ∗-η-Ricci-Yamabe Solitons

Advances in Mathematical Physics, 2022
In this note, we characterize Sasakian manifolds endowed with ∗-η-Ricci-Yamabe solitons. Also, the existence of ∗-η-Ricci-Yamabe solitons in a 5-dimensional Sasakian manifold has been proved through a concrete example.
