On the Schrödinger-Poisson system with $(p,q)$-LaplacianSong, Yueqiang (Avtor) Huo, Yuanyuan (Avtor) Repovš, Dušan (Avtor) double phase operatorSchrödinger-Poisson systems(pq)–Laplacianfixed point theoryWe study a class of Schrödinger-Poisson systems with $(p,q)$-Laplacian. Using fixed point theory, we obtain a new existence result for nontrivial solutions. The main novelty of the paper is the combination of a double phase operator and the nonlocal term. Our results generalize some known results.20232024-03-14 13:33:27Neznano18400UDK: 517.956.2ISSN pri članku: 0893-9659DOI: 10.1016/j.aml.2023.108595COBISS_ID: 140342787sl
