In this paper, we consider a class of fractional p -Laplacian system with three fractional critical Sobolev-Hardy exponents. By the Ekeland variational principle and the Mountain-Pass theorem, we study the existence and multiplicity of positive solutions to the system.

In this paper, using variational methods, we study the existence of ground states solutions to the modified fractional Schr¨odinger equations with a generalized Choquard nonlinearity
