Degeneration of Shrinking Ricci Solitons [PDF]

open access: yesInternational Mathematics Research Notices, 2010
Let $(Y,d)$ be a Gromov-Hausdorff limit of closed shrinking Ricci solitons with uniformly upper bounded diameter and lower bounded volume. We prove that off a closed subset of codimension at least 2, $Y$ is a smooth manifold satisfying a shrinking Ricci soliton equation.

On the blow-up of four-dimensional Ricci flow singularities [PDF]

open access: yes, 2013
textIn 2002, Feldman, Ilmanen, and Knopf constructed the first example of a non-trivial (i.e. non-constant curvature) complete non-compact shrinking soliton, and conjectured that it models a Ricci flow singularity forming on a closed four-manifold.

Some results of η-Ricci solitons on (LCS)n-manifolds [PDF]

open access: yesSurveys in Mathematics and its Applications, 2018
In this paper, we consider an η -Ricci soliton on the (LCS)n-manifolds (M, φ , ξ , η , g) satisfying certain curvature conditions likes: R(ξ , X) · S= 0 and W 2(ξ, X) · S=0.

Riemann Solitons on Homogeneous Siklos Spacetimes

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we investigate the properties of Riemann solitons on homogeneous Siklos spacetimes. Siklos spacetimes, which are special solutions to Einstein’s equations with a wave‐like potential, provide a suitable setting for studying the geometric properties of Riemann solitons.

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

open access: yes, 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 [PDF]

open access: yes, 2011
To every Ricci flow on a manifold over a time interval , we associate a shrinking Ricci soliton on the space-time . We relate properties of the original Ricci flow to properties of the new higher-dimensional Ricci flow equipped with its own time ...

Ricci Solitons and Generalized Ricci Solitons Whose Potential Vector Fields Are Jacobi‐Type

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
This paper is devoted to Ricci solitons admitting a Jacobi‐type vector field. First, we present some rigidity results for Ricci solitons (Mn, g, V, λ) admitting a Jacobi‐type vector field ξ and provide conditions under which ξ is Killing. We also present conditions under which the Ricci soliton (Mn, g, ξ, λ) is isometric to Rn.
