Claudianor O. Alves, Ronaldo C. Duarte, Marco Aurelio S. Souto

• In this paper we show an abstract theorem about the existence of critical points for a functional I, which permits us to prove the existence of solutions for a large class of Berestycki–Lions type problems. In the proof of the abstract result we apply the deformation lemma on a special set associated with I called Pohozaev set.
