Large number of bubble solutions for a perturbed fractional Laplacian equation

Chunhua Wang, Suting Wei

This paper deals with the following nonlinear perturbed fractional Laplacian equation $$(-\Delta {)}^{s}u=K(|y^{\prime }|,y^{\prime \prime })u^{\frac{N+2s}{N-2s}\pm \epsilon },u>0,u\in D^{1,s}({\mathbb{R}}^N),$$ wh…
