A New Complete Two-Dimensional Shrinking Gradient Kähler-Ricci Soliton

Geometric and Functional Analysis, 2022
We prove the existence of a unique complete shrinking gradient K\"ahler-Ricci soliton with bounded scalar curvature on the blowup of $\mathbb{C}\times\mathbb{P}^{1}$ at one point.

Conformal Submersions Whose Total Manifolds Admit a Ricci Soliton

Mediterranean Journal of Mathematics, 2022
In this paper, we study conformal submersions from Ricci solitons to Riemannian manifolds with non-trivial examples. First, we study some properties of the O’Neill tensor A in the case of conformal submersion.

Ricci soliton and geometrical structure in a perfect fluid spacetime with torse-forming vector field

Afrika Matematika, 2018
In this paper geometrical aspects of perfect fluid spacetime with torse-forming vector field $$\xi $$ξ are described and Ricci soliton in perfect fluid spacetime with torse-forming vector field $$\xi $$ξ are determined.

A note on almost Ricci soliton and gradient almost Ricci soliton on para-Sasakian manifolds

, 2020
The object of the offering exposition is to study almost Ricci soliton and gradient almost Ricci soliton in 3-dimensional para-Sasakian manifolds. At first, it is shown that if $(g, V,\lambda)$ be an almost Ricci soliton on a 3-dimensional para-Sasakian ...

RICCI-PSEUDOSYMMETRIC (LCS)n −MANIFOLDS ADMITTING ALMOST \(\eta\)−RICCI SOLITONS

Asian journal of mathematics and computer research, 2022
The objective of this paper is to study Ricci-pseudosymmetric (LCS)n −manifolds admitting almost \(\eta\)−Ricci solitons. We show that if a Ricci-pseudosymmetric (LCS)n −manifold admits \(\eta\)−Ricci soliton, then it is an \(\eta\)−Einstein and find the

Ricci almost solitons with associated projective vector field

Advances in Geometry, 2022
A Ricci almost soliton whose associated vector field is projective is shown to have vanishing Cotton tensor, divergence-free Bach tensor and Ricci tensor as conformal Killing.
