Gradient Kahler Ricci solitons

open access: yes, 2008
Some observations about the local and global generality of gradient Kahler Ricci solitons are made, including the existence of a canonically associated holomorphic volume form and vector field, the local generality of solutions with a prescribed ...

Boltzmann's Entropy and Kähler-Ricci Solitons

open access: yes, 2016
We study a Boltzmann's type entropy functional (which appeared in existing literature) defined on Kähler metrics of a fixed Kähler class. The critical points of this functional are gradient Kähler-Ricci solitons, and the functional was known to be ...

Classification of Gradient Ricci solitons with harmonic Weyl curvature

open access: yes, 2023
We make classifications of gradient Ricci solitons $(M, g, f)$ with harmonic Weyl curvature. As a local classification, we prove that the soliton metric $g$ is locally isometric to one of the following four types: an Einstein manifold, the Riemannian ...

Remarks on non-compact gradient Ricci solitons

open access: yes, 2011
In this paper we show how techniques coming from stochastic analysis, such as stochastic completeness (in the form of the weak maximum principle at infinity), parabolicity and Lp -Liouville type results for the weighted Laplacian associated to the ...

RICCI SOLITONS IN $\alfa$ COSYMPLECTIC MANIFOLDS

open access: yes, 2018
The object of the present paper is to study Ricci solitons in \alfacosymplectic manifolds. Projective, pseudo projective and Weyl conformal curvature in an \alfa cosymplectic manifolds admitting Ricci solitons have been studied under certain curvature ...

Rigidity of Complete Gradient Steady Ricci Solitons with Harmonic Weyl Curvature

open access: yes, 2023
Our main aim in this paper is to investigate the rigidity of complete noncompact gradient steady Ricci solitons with harmonic Weyl tensor. More precisely, we prove that an $n$-dimensional ($n\geq 5$) complete noncompact gradient steady Ricci soliton with

Gradient Kahler Ricci Solitons

open access: yes, 2004
Some observations about the local and global generality of gradient Kahler Ricci solitons are made, including the existence of a canonically associated holomorphic volume form and vector field, the local generality of solutions with a prescribed holomorphic volume form and vector field, and the existence of Poincare coordinates in the case that the ...

Siklos spacetimes as homogeneous Ricci solitons

open access: yes, 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.
