Existence of ground state solutions for fractional Choquard systems

open access: yes
This article studies the existence of ground state solutions for nonlinear fractional Choquard systems. Under Berestycki-Lions type assumptions on the nonlinearity, we develop a variational framework in fractional Sobolev spaces to tackle the system. The
