In this note we will generalize the results deduced in arXiv:1905.08203 and arXiv:2103.15360 to fractional Sobolev spaces. In particular we will show that for $s\in (0,1)$, $n>2s$ and $\nu\in \mathbb{N}$ there exists constants $\delta = \delta(n,s,\nu)>0$ and $C=C(n,s,\nu)>0$ such that for any function $u\in \dot{H}^s(\mathbb{R}^n)$ satisfying, \begin{align*} \left\| u-\sum_{i=1}^{\nu} \tilde{U}_{i}\right\|_{\dot{H}^s} \leq \delta \end{align*} where \$\tilde{U}_{1}, \tilde{U}_{2},\cdots \tilde{U… Expand

On the Sharp Stability of Critical Points of the Sobolev Inequality
• Physics, Mathematics
• 2019
Given $$n\ge 3$$ n ≥ 3 , consider the critical elliptic equation $$\Delta u + u^{2^*-1}=0$$ Δ u + u 2 ∗ - 1 = 0 in $${\mathbb {R}}^n$$ R n with $$u > 0$$ u > 0 . This equation corresponds to theExpand
Sharp quantitative estimates of Struwe's Decomposition
• Mathematics
• 2021
Suppose u ∈ Ḣ(R). In a fundamental paper [17], Struwe proved that if u ≥ 0 and ||∆u + u n+2 n−2 ||H−1 := Γ(u) → 0 then δ(u) → 0, where δ(u) denotes the Ḣ(R)-distance of u from the manifold of sums ofExpand
Best constant in Sobolev inequality
SummaryThe best constant for the simplest Sobolev inequality is exhibited. The proof is accomplished by symmetrizations (rearrangements in the sense of Hardy-Littlewood) and one-dimensional calculusExpand
