Geometry of almost *-η-Ricci-Yamabe soliton on Kenmotsu manifolds

Filomat
The goal of the present object is to study almost *-?-Ricci-Yamabe soliton within the framework of Kenmotsu manifolds. It is shown that if a Kenmotsu manifold admits a *-?-Ricci-Yamabe soliton, then it is ?-Einstein.

On almost generalized gradient Ricci-Yamabe soliton

Filomat
Inthis paper, we study the geometric characterizations and classify of the Riemannian manifold with generalized gradient Ricci-Yamabe soliton or almost generalized gradient Ricci-Yamabe soliton.

ALMOST CONTACT 3-MANIFOLDS AND RICCI SOLITONS

International Journal of Geometric Methods in Modern Physics, 2012
A Kenmotsu 3-manifold M admitting a Ricci soliton (g, w) with a transversal potential vector field w (orthogonal to the Reeb vector field) is of constant sectional curvature -1. A cosymplectic 3-manifold admitting a Ricci soliton with the Reeb potential vector field or a transversal vector field is of constant sectional curvature 0.

Ricci Solitons on Almost Co-Kähler Manifolds

Canadian Mathematical Bulletin, 2018
AbstractIn this paper, we prove that if an almost co-Kähler manifold of dimension greater than three satisfying $\unicode[STIX]{x1D702}$-Einstein condition with constant coefficients is a Ricci soliton with potential vector field being of constant length, then either the manifold is Einstein or the Reeb vector field is parallel.

Almost $��$-Ricci solitons on Kenmotsu manifolds

2020
In this paper we characterize the Einstein metrics in such broader classes of metrics as almost $ $-Ricci solitons and $ $-Ricci solitons on Kenmotsu manifolds, and generalize some results of other authors. First, we prove that a Kenmotsu metric as an $ $-Ricci soliton is Einstein metric if either it is $ $-Einstein or the potential vector field $V$

Yamabe Solitons and Ricci Solitons on Almost co-Kähler Manifolds

Canadian Mathematical Bulletin, 2019
AbstractThe object of this paper is to study Yamabe solitons on almost co-Kähler manifolds as well as on $(k,\unicode[STIX]{x1D707})$-almost co-Kähler manifolds. We also study Ricci solitons on $(k,\unicode[STIX]{x1D707})$-almost co-Kähler manifolds.

Almost Ricci solitons and $$K$$ K -contact geometry

Monatshefte für Mathematik, 2014
There are two theorems in this paper, both pertaining to almost Ricci solitons. The first one is actually a theorem of \textit{A. Barros} et al. [Monatsh. Math. 174, No. 1, 29--39 (2014; Zbl 1296.53092)] stating that a compact almost Ricci soliton with constant scalar curvature is gradient and isometric to a Euclidean sphere.

Goedesics Completeness and Cauchy Hypersurfaces of Ricci Solitons on Pseudo-Riemannian Hypersurfaces at the Fictitious Singularity: Schwarzschild-Soliton Geometries and Generalized-Schwarzschild-Soliton Ones

Axioms
The methodology is developed here to write Ricci solitons on the newly found structure of the pseudo-spherical cylinder. The methodology is specified for Schwarzschild solitons and for Generalized-Schwarzschild solitons. Accordingly, a new classification
