A spinorial energy functional: Critical points and gradient flow [PDF]

, 2012
On the universal bundle of unit spinors we study a natural energy functional whose critical points, if dimM C 3, are precisely the pairs (g,φ) consisting of a Ricci-flat Riemannian metric g together with a parallel g-spinor φ.

On Submanifolds of Riemannian Manifolds Admitting a Ricci Soliton [PDF]

Memoirs of the Scientific Sections of the Romanian Academy, 2019
The aim of this paper is to study the conditions under which a submanifold of a Ricci soliton is also a Ricci soliton or an almost Ricci soliton. We give here a classification for Ricci solitons and their submanifolds according to their expanding ...

Hyperbolic Ricci soliton and gradient hyperbolic Ricci soliton on relativistic prefect fluid spacetime

AIMS Mathematics
In this research note, we investigated the characteristics of perfect fluid spacetime when coupled with the hyperbolic Ricci soliton. We additionally interacted with the perfect fluid spacetime, with a $ \varphi(\mathcal{Q}) $-vector field and a bi ...

Characterization of a hyperbolic Ricci soliton on sequential warped product manifold

Gulf Journal of Mathematics
The destination of the paper is to analyze a hyperbolic Ricci soliton on sequential warped product manifold. We investigate the necessary condition for a hyperbolic Ricci soliton on sequential warped product to become an Einstein manifold when the ...

Curvature growth of some 4-dimensional gradient Ricci soliton singularity models [PDF]

Advances in Mathematics, 2019
In this note we discuss estimates for the curvature of 4-dimensional gradient Ricci soliton singularity models by applying Perelman's point selection, a fundamental result of Cheeger and Naber, and topological lemmas.

On Ricci solitons in LP-Sasakian manifolds

Bibechana, 2020
In this paper we study Ricci solitons in Lorentzian para-Sasakian manifolds. It is proved that the Ricci soliton in a (2n+1)-dimensinal LP-Sasakian manifold is shrinking.

Ricci Solitons in β-Kenmotsu Manifolds

Annals of the West University of Timisoara: Mathematics and Computer Science, 2018
The object of the present paper is to study Ricci soliton in β-Kenmotsu manifolds. Here it is proved that a symmetric parallel second order covariant tensor in a β-Kenmotsu manifold is a constant multiple of the metric tensor.

Modified Ricci flow on a principal bundle [PDF]

, 2008
textLet M be a Riemannian manifold with metric g, and let P be a principal G-bundle over M having connection one-form a. One can define a modified version of the Ricci flow on P by fixing the size of the fiber.
