The existence of the Kähler–Ricci soliton degeneration [PDF]
Forum of Mathematics, Pi, 2021 We prove an algebraic version of the Hamilton–Tian conjecture for all log Fano pairs. More precisely, we show that any log Fano pair admits a canonical two-step degeneration to a reduced uniformly Ding stable triple, which admits a Kähler–Ricci soliton ...

Ricci Soliton of CR-Warped Product Manifolds and Their Classifications
Symmetry, 2023 In this article, we derived an equality for CR-warped product in a complex space form which forms the relationship between the gradient and Laplacian of the warping function and second fundamental form.

Riemannian maps whose base manifolds admit a Ricci soliton [PDF]
Publicationes mathematicae (Debrecen), 2021 In this paper, we study Riemannian maps whose base manifolds admit a Ricci soliton and give a non-trivial example of such Riemannian maps. First, we find Riemannian curvature tensor of base manifolds for Riemannian map $F$.

Karpatsʹkì Matematičnì Publìkacìï, 2023 The goal of this paper is to find some important Einstein manifolds using conformal Ricci solitons and conformal Ricci almost solitons. We prove that a Kenmotsu metric as a conformal Ricci soliton is Einstein if it is an $\eta$-Einstein or the potential ...

Existence of Finite Global Norm of Potential Vector Field in a Ricci Soliton [PDF]
Proceedings of the National Academy of Sciences India Section A Physical Sciences, 2021 In this paper, we present global norm of potential vector field in Ricci soliton. In particular, we deduce certain conditions so that the potential vector field has finite global norm in expanding Ricci soliton. In addition, we show that if the potential

A note on gradient Ricci soliton warped metrics [PDF]
Mathematische Nachrichten, 2021 In this note, we prove triviality and nonexistence results for gradient Ricci soliton warped metrics. The proofs stem from the construction of gradient Ricci solitons that are realized as warped products, from which we know that the base spaces of these ...

Almost Ricci–Bourguignon Solitons on Doubly Warped Product Manifolds
Universe, 2023 This study aims at examining the effects of an almost Ricci–Bourguignon soliton structure on the base and fiber factor manifolds of a doubly warped product manifold.

Gulf Journal of Mathematics, 2022 Abstract. In the present paper, we prove three fundamental results concerning almost ∗-Ricci soliton in the framework of para-Sasakian manifold. The paper is organised as follows:• If a para-Sasakian metric g represents an almost ∗-Ricci soliton with potential vector field V is Jacobi along Reeb vector field ξ, then g becomes a ∗-Ricci soliton.• If a ...

On the Yau‐Tian‐Donaldson Conjecture for Generalized Kähler‐Ricci Soliton Equations [PDF]
Communications on Pure and Applied Mathematics, 2020 Let (X,D) be a polarized log variety with an effective holomorphic torus action, and Θ be a closed positive torus invariant (1,1) ‐current. For any smooth positive function g defined on the moment polytope of the torus action, we study the Monge‐Ampère ...
