Abstract:

Goal of this paper is to study the following doubly nonlocal equation \label{eqabstract} (- \Delta)s u + \mu u = (I\alphaF(u))F'(u) \quad \hbox{in $\mathbb{R}^N$} \tag{P} in the case of general nonlinearities $F \in C^1(\mathbb{R})$ of Berestycki-Lions type, when $N \geq 2$ and $\mu>0$ is fixed. Here $(-\Delta)^s$, $s \in (0,1)$, denotes the fractional Laplacian, while the Hartree-type term is given by convolution with the Riesz potential $I_{\alpha}$, $\alpha \in (0,N)$. We prove existence of ground states of \eqref{eqabstract}. Furthermore we obtain regularity and asymptotic decay of general solutions, extending some results contained in 25, 65.
