Abstract

We study the asymptotic and qualitative properties of least energy radial sign-changing solutions to fractional semilinear elliptic problems of the form

$ \begin{cases} (-\Delta)^s u = |u|^{2^*_s-2-\varepsilon}u &\text{in } B_R, \\ u = 0 &\text{in } \mathbb{R}^n \setminus B_R, \end{cases} $

where $ s \in (0,1) $, $ (-\Delta)^s $ is the s-Laplacian, $ B_R $ is a ball of $ \mathbb{R}^n $, $ 2^*_s : = \frac{2n}{n-2s} $ is the critical Sobolev exponent and $ \varepsilon>0 $ is a small parameter. We prove that such solutions have the limit profile of a "tower of bubbles", as $ \varepsilon \to 0^+ $, i.e. the positive and negative parts concentrate at the same point with different concentration speeds. Moreover, we provide information about the nodal set of these solutions.
