Abstract: In the present paper, we study the existence of multiple solutions for a nonlinear Choquard equation in the presence of a magnetic field. Using variational methods, penalization techniques and Ljusternik–Schnirelmann theory, we relate the number of solutions with the topology of the set where the potential attains its minimum value.

Keywords: Choquard equation, magnetic field, variational methods, penalization techniques, Ljusternik–Schnirelmann theory
