Multiple positive solutions with prescribed masses for a coupled SchrÃ¶dinger system: mass mixed and Sobolev critical coupled case

Qing Guo, Qihan He, Wei Shuai +1

The aim of this paper is to establish multiple positive normalized solutions $(u, v, I^»_{1}, I^»_{2}) \in H^{1} (R^{N}, R^{2}) \times R^{2}$ to the following coupled SchrÃ¶d…

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…
