Equivariant Yamabe problem with boundary [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2022
AbstractAs a generalization of the Yamabe problem, Hebey and Vaugon considered the equivariant Yamabe problem: for a subgroupGof the isometry group, find aG-invariant metric whose scalar curvature is constant in a given conformal class. In this paper, we study the equivariant Yamabe problem with boundary.

The k-Yamabe problem [PDF]

open access: yesSurveys in Differential Geometry, 2012
1.1. The k-Yamabe problem. The k-Yamabe problem is a higher order extension of the celebrated Yamabe problem for scalar curvature. It was initially proposed by Viaclovsky [72] and also arose in the study of Q-curvatures in [11]. Viaclovsky found that in a conformal metric, the resultant k-curvature equation can be expressed as an equation similar to ...

A Problem Concerning Yamabe-Type Operators of Negative Admissible Metrics

open access: yesJournal of Applied Mathematics, 2012
This paper is about a problem concerning nonlinear Yamabe-type operators of negative admissible metrics. We first give a result on σk Yamabe problem of negative admissible metrics by virtue of the degree theory in nonlinear functional analysis and the ...

Group Actions On The Sphere And Multiplicity Results For The Cr-Yamabe Equation

open access: yesBruno Pini Mathematical Analysis Seminar, 2015
We will show that the CR-Yamabe equation has several families of infinitely many changing sign solutions, each of them having different symmetries. The problem is variational but it is not Palais-Smale: using different complex group actions on the sphere,

Generic Properties of Critical Points of the Weyl Tensor

open access: yesAdvanced Nonlinear Studies, 2017
Given (M,g)${(M,g)}$, a smooth compact Riemannian n-manifold, we prove that for a generic Riemannian metric g the critical points of the function 𝒲g⁢(ξ):=|Weylg⁢(ξ)|g2${\mathcal{W}_{g}(\xi):=\lvert\mathrm{Weyl}_{g}(\xi)\rvert^{2}_{g}}$ with 𝒲g⁢(ξ)≠0 ...

Hardy-Littlewood-Sobolev inequalities on compact Riemannian manifolds and applications

open access: yes, 2015
In this paper we extend Hardy-Littlewood-Sobolev inequalities on compact Riemannian manifolds for dimension $n\ne 2$. As one application, we solve a generalized Yamabe problem on locally conforamlly flat manifolds via a new designed energy functional and
