Extremals for Fractional Moser–Trudinger Inequalities in Dimension 1 via Harmonic Extensions and Commutator Estimates

open access: yesAdvanced Nonlinear Studies, 2020
We prove the existence of extremals for fractional Moser–Trudinger inequalities in an interval and on the whole real line. In both cases we use blow-up analysis for the corresponding Euler–Lagrange equation, which requires new sharp estimates obtained ...

Compactness results for prescribed Webster scalar curvature problem on CR sphere

open access: yesAdvances in Nonlinear Analysis
In this paper we prove some results on the compactness of solutions to the prescribed Webster scalar curvature problem on S3,θ0 $\left({\mathbb{S}}^{3},{\theta }_{0}\right)$ . We first combine blow-up analysis with the subcritical approximation method to
