The Existence of Gradient Yamabe Solitons on Spacetimes
Results in Mathematics, 2022The authors investigate the existence of the non-trivial gradient Yamabe soliton on generalized Robertson-Walker spacetimes, standard static spacetimes, Walker manifolds and pp-wave spacetimes. The most remarkable results concern gradient Yamabe solitons on pp-wave spacetimes (see Section 3.5).

On Finslerian Warped Product Gradient Yamabe Solitons
Bulletin of the Brazilian Mathematical Society, New Series, 2022In the present paper the authors study the Finslerian gradient Yamabe solitons on warped product manifolds. Firstly, the authors present some rigidity results related to the warping and potential functions and in order to provide nontrivial examples, they consider the warped product base as a double twisted product invariant by the action of a ...

Characterizations of Gradient h-Almost Yamabe Solitons
Results in Mathematics, 2022A Riemannian manifold \(\left(M,g\right)\) is called a Yamabe soliton if there is a vector field \(X\) on \(M\) such that \(\frac{1}{2}\mathcal{L}_{X}g=\left(R-\lambda\right)g\), where \(\mathcal{L}_{X}\) is the Lie derivative in the direction of the vector field \(X\), \(\lambda\in\mathbb{R}\) and \(R\) is the scalar curvature of \(\left(M,g\right)\).

\textit{S. Güler} and \textit{M. Crasmareanu} [Turk. J. Math. 43, No. 5, 2631--2641 (2019; Zbl 1433.53125)] introduced a new geometric flow under the name of Ricci-Yamabe flow because it is a scalar combination of the well-known Ricci and Yamabe flows. The paper under review is concerned with the notion of \(\eta \)-Ricci-Yamabe soliton in the setting ...

On Gradient Ricci-Yamabe Solitons
Iranian Journal of ScienceIn this paper, we establish some necessary and sufficient conditions for multiply warped product manifolds admitting a gradient Ricci-Yamabe soliton. For this purpose, the potential function of this soliton and the conditions that must be satisfied for each component of the multiply warped product manifold are investigated.

Yamabe solitons and gradient Yamabe solitons on three-dimensional N(k)-contact manifolds
International Journal of Geometric Methods in Modern Physics, 2020If a three-dimensional [Formula: see text]-contact metric manifold [Formula: see text] admits a Yamabe soliton of type [Formula: see text], then the manifold has a constant scalar curvature and the flow vector field [Formula: see text] is Killing. Furthermore, either [Formula: see text] has a constant curvature [Formula: see text] or the flow vector ...

Geometry of gradient Yamabe solitons
Annals of Global Analysis and Geometry, 2016Let \((M,g)\) be a complete Riemannian manifold. The Riemannian metric \(g=g_{ij}dx^idx^j\) is called a gradient Yamabe soliton if there exists a smooth function \(f:M\longrightarrow\mathbb{R}\) and a constant \(\lambda\in\mathbb{R}\) such that \[ (R-\lambda)g_{ij}=\nabla_i\nabla_jf, \] where \(R\) denotes the scalar curvature of the Riemannian metric \
