∗-Ricci Soliton within the frame-work of Sasakian and (κ,μ)-contact manifold

, 2018
We prove that if a Sasakian metric is a ∗-Ricci Soliton, then it is either positive Sasakian, or null-Sasakian. Next, we prove that if a complete Sasakian metric is an almost gradient ∗-Ricci Soliton, then it is positive-Sasakian and isometric to a unit

The canonical shrinking soliton associated to a Ricci flow

, 2020
To every Ricci flow on a manifold M over a time interval I ⊂ R−, we associate a shrinking Ricci soliton on the space-time M×I. We relate properties of the original Ricci flow to properties of the new higher-dimensional Ricci flow equipped with its own ...

On h-almost conformal η-Ricci-Bourguignon soliton in a perfect fluid spacetime

The primary object of the paper is to study h-almost conformal η-Ricci-Bourguignon soliton in an almost pseudo-symmetric Lorentzian Kähler spacetime manifold when some different curvature tensors vanish identically.

D-homothetically deformed Kenmotsu metric as a Ricci soliton

, 2018
In this paper we study the nature of Ricci solitons in D-homothetically deformed Kenmotsu manifolds. We prove that η-Einstein Kenmotsu metric as a Ricci soliton remains η-Einstein under D-homothetic deformation and the scalar curvature remains ...

Some Properties of the Potential Field of an Almost Ricci Soliton

Mathematics
In this article, we are interested in finding necessary and sufficient conditions for a compact almost Ricci soliton to be a trivial Ricci soliton. As a first result, we show that positive Ricci curvature and, for a nonzero constant c, the integral of ...
