The prescribed Gauduchon scalar curvature problem in almost Hermitian geometry [PDF]

open access: yesScience China Mathematics, 2023
In this paper we consider the prescribed Gauduchon scalar curvature problem on almost Hermitian manifolds. By deducing the expression of the Gauduchon scalar curvature under the conformal variation, the problem is reduced to solve a semi-linear partial differential equation with exponential nonlinearity.

Topological tools for the prescribed scalar curvature problem on S n

open access: yesOpen Mathematics, 2014
AbstractIn this paper, we consider the problem of the existence of conformal metrics with prescribed scalar curvature on the standard sphere S n, n ≥ 3. We give new existence and multiplicity results based on a new Euler-Hopf formula type. Our argument also has the advantage of extending well known results due to Y. Li [16].

The Prescribed Chern Scalar Curvature Problem [PDF]

open access: yesThe Journal of Geometric Analysis, 2022
AbstractThe paper is an attempt to resolve the prescribed Chern scalar curvature problem. We look for solutions within the conformal class of a fixed Hermitian metric. We divide the problem in three cases, according to the sign of the Gauduchon degree, that we analyse separately.

Doubling the equatorial for the prescribed scalar curvatureproblem on ${\mathbb{S}}^N$ [PDF]

open access: yesNonlinear Differential Equations and Applications NoDEA, 2023
Abstract Note: Please see pdf for full abstract with equations. We consider the prescribed scalar curvature problem on SN ΔSN v −N(N − 2)/2 v + ​​K̃ (y)v N+2/N−2 = 0 on SN, v > 0 in SN, under the assumptions that the scalar curvature ​K̃ is rotationally symmetric, and has a positive local maximum point between the poles.

On the singular prescribed scalar curvature problem [PDF]

open access: yes, 2023
Let (M, g) be a compact Riemannian manifold of dimension \(n \geq3\). In this paper, we define and introduce the prescribed scalar curvature problem with singularities. Under some assumptions, we show that there exists a conformal metric \(\overline{g}\) such that its scalar curvature \(S_{\overline{g}}\) equals some given function.

On the Chen–Lin Conjecture for the Prescribed Scalar Curvature Problem

open access: yesThe Journal of Geometric Analysis, 2023
We prove a criterion of existence of solutions conjectured by C. C. Chen and C. S. Lin [20] for the prescribed scalar curvature problem on the standard n-dimensional sphere.

Prescribed scalar curvature problem on complete manifolds

open access: yesJournal de Mathématiques Pures et Appliquées, 1999
Summary: Conditions on the geometric structure of a complete Riemannian manifold are given to solve the prescribed scalar curvature problem. In some cases, the conformal metric obtained is complete. A minimizing sequence is constructed which converges strongly to a solution.

On the prescribed scalar curvature problem on 4-manifolds

open access: yesDuke Mathematical Journal, 1996
This work gives a complete and detailed proof of the result stated in the appendix of the paper of \textit{A. Bahri} and \textit{J. M. Coron} [J. Funct. Anal. 95, No. 1, 106-172 (1991; Zbl 0722.53032)]. The key part in the proof is to find a good pseudo-gradient flow. This is hard work. To do this, they need to find a good Morse lemma at bubbles. It is
