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 Kähler-Ricci soliton with bounded scalar curvature on the blowup of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb ...

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.

Extremals of Log Sobolev inequality on non-compact manifolds and Ricci soliton structures

Calculus of Variations and Partial Differential Equations, 2016
In this paper we establish the existence of extremals for the Log Sobolev functional on complete non-compact manifolds with Ricci curvature bounded from below and strictly positive injectivity radius, under a condition near infinity.

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.

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

Steady Gradient Kähler-Ricci Solitons on Crepant Resolutions of Calabi-Yau Cones

Memoirs of the American Mathematical Society, 2020
We show that, up to the flow of the soliton vector field, there exists a unique complete steady gradient Kähler-Ricci soliton in every Kähler class of an equivariant crepant resolution of a Calabi-Yau cone converging at a polynomial rate to Cao’s steady ...
