Multiple solutions for a fractional p-Laplacian equation with sign-changing potential

Vincenzo Ambrosio

We use a variant of the fountain Theorem to prove the existence of infinitely many weak solutions for the fractional p-Laplace equation
 (-\Delta)_p^s u + V(x) |u|^{p-2}u = f(x, u) \quad \text{in }  \mathbb{R}^N,
where $s\in (0,1)$, $p\geq 2$, $N\geq 2$, $(- \Delta)_{p}^s$ is the fractional p-Laplace operator, the nonlinearity f is p-superlinear at infinity and the potential V(x) is allowed to be sign-changing.
