  • Multiple solutions with sign information for superlinea ▫$(p, q)$▫-equations
    Liu, Zhenhai ; Papageorgiou, Nikolaos, 1958-
    We consider a nonlinear Dirichlet problem driven by the ▫$(p, q)$▫-Laplacian and with a Carathéodory reaction ▫$f(z, x)$▫ which is ▫$(p-1)$▫-superlinear in ▫$x \in \mathbb{R}$▫ but without satisfying ... the Ambrosetti-Rabinowitz condition. Using variational tools and critical groups, we prove a multiplicity theorem producing three nontrivial smooth solutions all with sign information (one positive, one negative and one nodal).
