Infinitely many free or prescribed mass solutions for fractional Hartree equations and Pohozaev identities

Silvia Cingolani, Marco Gallo, Kazunaga Tanaka

In this paper we study the following nonlinear fractional Choquard-Pekar equation \begin{equation}\label{eq_abstract} (-Δ)^s u + μu =(I_α*F(u)) F'(u) \quad \hbox{in}\ \mathbb{R}^N,…
