In this paper, we consider fractional CR Yamabe type equations of order 2γ, 0 γ n + 1 , on the standard CR Manifold ( S 2 n + 1 , θ 0 ) , n ≥ 1 . By studying the asymptotic behaviors of the associated pseudo-gradient flows, we give a complete de

In this paper we deal with the scalar curvature problem under minimal boundary mean curvature condition on the standard 3-dimensional half-sphere. Using tools related to the theory of critical points at infinity, we give existence results under pertu

This paper is about prescribing the Webster scalar curvature on a compact CR manifold of dimension 2n+1 ≥ 5, which is locally CR equivalent to the standard CR unit sphere S2n+1. The associated variational problem being noncompact we approach this i

In this Note, we give two new perturbative results for prescribing the Webster scalar curvature on the ( 2 n + 1 ) -dimensional sphere endowed with its standard CR structure. The first result generalizes the one obtained by A. Malchiodi and F. Uguzzo

In this paper, we consider the problem of existence as well as multiplicity results for a bi-harmonic equation under the Navier boundary conditions: Δ2u = K(x)up, u > 0 in Ω, Δu = u = 0 on ∂Ω, where Ω is a smooth domain in ℝn,n≥5, and p+1=

We consider the existence of contact forms of prescribed Webster scalar curvature on a (2n+1)-dimensional CR compact manifold locally conformally CR equivalent to the standard unit sphere S2n+1 of Cn+1. We give some existence results, using dynamical

In order to study the scalar curvature problem on spheres Sn of dimension n ≥ 7, A. Bahri introduced, in [4], an invariant for Yamabe-type or scalar curvature flows. In this paper, we show that this invariant is not particularly related to Yamabe-t
