  • On a Robin ▫$(p,q)$▫-equation with a logistic reaction
    Papageorgiou, Nikolaos, 1958- ; Vetro, Calogero ; Vetro, Francesca
    We consider a nonlinear nonhomogeneous Robin equation driven by the sum of a ▫$p$▫-Laplacian and of a ▫$q$▫-Laplacian (▫$(p,q)$▫-equation) plus an indefinite potential term and a parametric reaction ... of logistic type (superdiffusive case). We prove a bifurcation-type result 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 admits a smallest positive solution.
