In this paper, we consider the Brezis-Nirenberg problem for the nonlocal fractional elliptic equation Aαux=NN-2αuxp+εux, x∈Ω, ux>0, x∈Ω, u(x)=0, x∈∂Ω, where 0<α<1 is fixed, p=N+2α/N-2α, ε is a small parameter, and Ω is a bounded smooth domain of RN(N≥4α). Aα denotes the fractional Laplace operator defined through the spectral decomposition. Under some geometry hypothesis on the domain Ω, we show that all solutions to this problem are least energy solutions.

For $$s \in (0,1)$$ s ∈ ( 0 , 1 ) , $$N > 2s$$ N > 2 s , and a bounded open set $$\Omega \subset {\mathbb {R}}^N$$ Ω ⊂ R N with $$C^2$$ C 2 boundary, we study the fractional Brezis–Nirenberg type minimization problem of finding $$\begin{aligned} S(a):= \inf \frac{\int _{{\mathbb {R}}^N} |(-\Delta )^{s/2} u|^2 + \int _\Omega a u^2}{\left( \int _\Omega u^\frac{2N}{N-2s} \right) ^\frac{N-2s}{N}}, \end{aligned}$$ S ( a ) : = inf ∫ R N | ( - Δ ) s / 2 u | 2 + ∫ Ω a u 2 ∫ Ω u 2 N N - 2 s N - 2 s N , where the infimum is taken over all functions $$u \in H^s({\mathbb {R}}^N)$$ u ∈ H s ( R N ) that vanish outside $$\Omega $$ Ω . The function a is assumed to be critical in the sense of Hebey and Vaugon. For low dimensions $$N \in (2\,s, 4\,s)$$ N ∈ ( 2 s , 4 s ) , we prove that the Robin function $$\phi _a$$ ϕ a satisfies $$\inf _{x \in \Omega } \phi _a(x) = 0$$ inf x ∈ Ω ϕ a ( x ) = 0 , which extends a result obtained by Druet for $$s = 1$$ s = 1 . In dimensions $$N \in (8s/3, 4s)$$ N ∈ ( 8 s / 3 , 4 s ) , we then study the asymptotics of the fractional Brezis–Nirenberg energy $$S(a + \varepsilon V)$$ S ( a + ε V ) for some $$V \in L^\infty (\Omega )$$ V ∈ L ∞ ( Ω ) as $$\varepsilon \rightarrow 0+$$ ε → 0 + . We give a precise description of the blow-up profile of (almost) minimizing sequences and characterize the concentration speed and the location of concentration points.
