  • Singular ▫$(p,q)$▫-equations with competing perturbations
    Papageorgiou, Nikolaos, 1958- ; Zhang, Chao, 1981-
    We consider a nonlinear Dirichlet problem driven by the ▫$(p,q)$▫-Laplacian and with a reaction involving the combined effects of a singular term, of a concave term and of a parametric convex term. ... We prove a bifurcation-type theorem describing the changes in the set of positive solutions as the parameter ▫$\lambda > 0$▫ varies. Also, we show that for every admissible parameter ▫$\lambda > 0$▫, the problem has a minimal positive solution ▫$u^\ast_\lambda$▫ and we establish the monotonicity and continuity properties of the map ▫$\lambda \to u^\ast_\lambda$▫.
