报告摘要: We establish fine bounds for best constants of the fractional subcritical Sobolev embeddings \begin{align*}W_{0}^{s,p}\left(\Omega\right)\hookrightarrowL^{q}\left(\Omega\right),\end{align*}Where $0<s\leq1$, $N\geq1$, $1\leq p\leq \frac{N}{s}$, and $\Omega\subset\mathbb{R}^{N}$ is a bounded smooth domain or the whole space $\mathbb{R}^{N}$. Moreover, we apply the obtained results to prove existence and non-existence of solutions for a wide class of nonlocal partial differential equations.
