The concentration-compactness principle is applied to show the compactness. As a byproduct, we obtain the uniqueness of the positive ground state solution for a class of autonomous Hamiltonian systems and the best constant for Sobolev inequality which are of independent interests. date: 2023 type: Folyóirat type: NonPeerReviewed format: full language: hu identifier: http://acta.bibl.u-szeged.hu/82281/1/ejqtde_2023_031.pdf identifier: Wu Dong-Lun: Homoclinic solutions for a class of asymptotically autonomous Hamiltonian systems with indefinite sign nonlinearities.
