Two-bubble nodal solutions for slightly subcritical Fractional Laplacian

In this paper, we consider the existence of nodal solutions with two bubbles to the slightly subcritical problem with the fractional Laplacian \begin{equation*} \left\{\aligned &(-Δ)^su=|u|^{p-1-\varepsilon}u\ \ \mbox{in}\ Ω&u=0\ \mbox{on}\ \partialΩ, \endaligned \right. \end{equation*} where $Ω$ is a smooth bounded domain in $\mathbb R^N$, $N>2s$, $0<s<1$, $p=\frac{N+2s}{N-2s}$ and $\varepsilon>0$ is a small parameter, which can be seen as a nonlocal analog of the results of Bartsch, Micheletti and Pistoia (2006) \cite{Bartsch1}.
