Abstract
In this paper, we study the asymptotic properties of solutions for the constrained minimization problems.
First, when \(\lim _{p\nearrow 2s}b_p=b<b^*\), the set of minimizers of \(d_{b_p}(p)\) is compact in a suitable space as \(p\nearrow 2s\). In addition, when \(\lim _{p\nearrow 2s}b_p=b\ge b^*\), by developing suitable trial functions for some fine energy estimates, we prove that all minimizers must blow up and give decay properties of minimizers.
本文研究了受约束最小化问题解的渐近特性。$$\begin{aligned} d_{b_p}(p):=\inf _\{u\in H^s_V({\mathbb {R}}^2):\int _{{mathbb {R}}^2}|u|^2dx=1\}}I_{p,b_p}(u), \end{aligned}$$ 其中 \(s\in (\frac{1}{2},1),\)\(p\in (0, 2s)\),\(b_p>0\) and $$$\begin{aligned}I_{p,b_p}(u){:=}\frac{1}{2}\int _{{\mathbb {R}}^2}}\left( |(-\Delta )^{\frac{s}{2}}}u|^2{+}V(x)|u|^2\right) dx{-}\frac{b_p}{p+2}\int _{{\mathbb {R}}^2}|u|^{p+2}dx,\quad u\in H^s_V({\mathbb {R}}^2).\end{aligned}$$First, when \(\lim _{p\nearrow 2s}b_p=b<b^*\), the set of minimizers of \(d_{b_p}(p)\) is compact in a suitable space as \(p/nearrow 2s\)。此外,当 \(\lim _{p\nearrow 2s}b_p=b\ge b^*\)时,通过为一些精细的能量估计建立合适的试函数,我们证明了所有的最小值都必须炸毁,并给出了最小值的衰变特性。
