  • On a Dirichlet problem with ▫$(p,q)$▫-Laplacian and parametric concave-convex nonlinearity
    Marano, Salvatore Angelo ; Marino, Greta ; Papageorgiou, Nikolaos, 1958-
    A homogeneous Dirichlet problem with ▫$(p, q)$▫-Laplace differential operator and reaction given by a parametric ▫$p$▫-convex term plus a ▫$q$▫-concave one is investigated. A bifurcation-type result, ... describing changes in the set of positive solutions as the parameter ▫$\lambda > 0$▫ varies, is proven. Since for every admissible ▫$\lambda$▫ the problem has a smallest positive solution ▫$\bar{u}_\lambda$▫, both monotonicity and continuity of the map ▫$\lambda \mapsto\bar{u}_\lambda$▫ are studied.
