On some nonlinear fractional equations involving the Bessel operator

Under different assumptions on the potential functions $b$ and $c$, we study the fractional equation $\left( I-\Delta \right)^{\alpha} u = \lambda b(x) |u|^{p-2}u+c(x)|u|^{q-2}u$in$$\mathbb{R}$^N$. Our existence results are based on compact embedding properties for weighted spaces.
