A New Complete Two-Dimensional Shrinking Gradient Kähler-Ricci Soliton
Geometric and Functional Analysis, 2022We 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, 2022In 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.

Conformal Ricci soliton and almost conformal Ricci soliton in paracontact geometry
International Journal of Geometric Methods in Modern Physics (IJGMMP), 2022In this paper, we study conformal Ricci soliton and almost conformal Ricci soliton within the framework of paracontact manifolds. Here, we have shown the characteristics of the soliton vector field and the nature of the manifold if para-Sasakian metric ...

Ricci soliton vector fields of Kantowski–Sachs spacetimes
Modern Physics Letters A, 2022In this paper our focus is on exploring the Ricci solitons of the Kantowski–Sachs spacetime. All the obtained Ricci solitons are expanding only. Also in all the cases except one case, Ricci soliton manifolds are Einstein and hence the Ricci solitons are ...

Solutions of the Ricci soliton equation for a large class of Siklos spacetimes
, 2021We determine and describe all the Ricci solitons within a very large class of Siklos metrics. As an application, the Ricci soliton equation is completely solved for several classes of Siklos metric...

Remarks on Kähler–Ricci solitons
Advances in Geometry, 2015Abstract We prove that a compact complex manifold endowed with a Kähler-Ricci soliton cannot be isometrically embedded in a complex projective space ℂℙn in such a way that the Gauss map is rational, unless the metric is Einstein. This applies to hypersurfaces of complex compact homogeneous spaces canonically embedded in ℂℙn.We moreover ...

LCS-manifolds and Ricci solitons
International Journal of Geometric Methods in Modern Physics, 2021This paper is concerned with the study of [Formula: see text]-manifolds and Ricci solitons. It is shown that in a [Formula: see text]-spacetime, the fluid has vanishing vorticity and vanishing shear. It is found that in an [Formula: see text]-manifold, [Formula: see text] is an irrotational vector field, where [Formula: see text] is a non-zero smooth ...

Conformal Ricci soliton and geometrical structure in a perfect fluid spacetime
, 2020In this paper, we studied the geometrical aspects of a perfect fluid spacetime in terms of conformal Ricci soliton and conformal η-Ricci soliton with torse-forming vector field ξ.
