Infinitely many non-radial sign-changing solutions for a Fractional Laplacian equation with critical nonlinearity

Fei Fang

In this work, the following fractional Laplacian problem with pure critical nonlinearity is considered \begin{equation*} \left\{ \begin{array}{ll} (-Δ)^{s} u=|u|^{\frac{4s}{N-2s}}u…
