Bivariate Hardy-Sobolev Inequality and Its Sharp Stability

Yingfang Zhang, Xuexiu Zhong, Wenming Zou

This paper establishes a bivariate Hardy-Sobolev inequality. Let $I^c ◯ \subset R^{N}$ ( $N \geq 3$ ) be an open domain, $s \in (0, 2)$ , $I^\pm > 1$ , $I^^{2} > 1$ with $I^\pm + I^^{2} = 2^{*} (s)$ , and…

Sharp quantitative stability for the fractional Sobolev trace inequality

Yingfang Zhang, Yuxuan Zhou, Wenming Zou

In this paper, we study the stability of fractional Sobolev trace inequality within both the functional and critical point settings. In the functional setting, we establish the fol…

A strong-form stability for a class of $L^{p}$ Caffarelli-Kohn-Nirenberg interpolation inequality

Yingfang Zhang, Wenming Zou

We study the stability of a class of Caffarelli-Kohn-Nirenberg (CKN) interpolation inequality and establish a strong-form stability as following: \begin{equation*} \inf_{v\in\mathc…
