To this end we use variational methods combined with the Mountain pass theorem and the Ekeland variational principle. We illustrate the usefulness of our results with an example.20232023-09-26 13:38:54Članek v reviji150993UDK: 517.9ISSN pri članku: 1072-6691DOI: 10.58997/ejde.2023.61COBISS_ID: 165693699slPodatek o licenci CC-BY je naveden na prvi strani članka.
