Maximum principles and gradient Ricci solitons

, 2011
It is shown that the Omori–Yau maximum principle holds true on complete gradient shrinking Ricci solitons both for the Laplacian and the f-Laplacian. As an application, curvature estimates and rigidity results for shrinking Ricci solitons are obtained ...

Exploring Conformal Soliton Structures in Tangent Bundles with Ricci-Quarter Symmetric Metric Connections

Mathematics
In this study, we investigate the tangent bundle TM of an n-dimensional (pseudo-)Riemannian manifold M equipped with a Ricci-quarter symmetric metric connection ∇˜.

Siklos spacetimes as homogeneous Ricci solitons

, 2019
We consider a well-known class of homogeneous solutions of the Einstein–Maxwell equations found by Siklos and prove that all these spacetimes are nontrivial Ricci solitons.

Gradient Expanding Ricci Solitons Type Inequalities on Submanifolds in Quaternion Kaehler Manifolds with Bi-Slant Factor

Mathematics
In this article, we study the Ricci soliton on quaternion bi-slant submanifolds of quaternion Kaehler manifolds. We obtain a lower-bound-type inequality in terms of expanding gradient Ricci solitons with a gradient-type vector field for the quaternion bi-

Geometry of Ricci–Bourguignon Solitons on Mixed Doubly Sequential Warped Products: Existence, Classification, and Cosmological Implications

Axioms
We investigate Ricci–Bourguignon solitons on mixed doubly sequential warped product manifolds. Necessary and sufficient conditions for the existence of such solitons are established, and their implications for Einstein manifolds are analyzed.

A Solitonic Approach of General Relativistic Spacetimes with Applications

Axioms
In this article, some remarkable results on general relativistic spacetimes with non-constant scalar curvature τ, admitting almost Ricci-Bourguignon solitons and gradient almost Ricci-Bourguignon solitons, have been established.
