  • Singular ▫$(p, q)$▫-equations with superlinear reaction and concave boundary condition
    Papageorgiou, Nikolaos, 1958- ; Vetro, Calogero ; Vetro, Francesca
    We consider a parametric nonlinear elliptic problem driven by the sum of a ▫$p$▫-Laplacian and of a ▫$q$▫-Laplacian (a ▫$(p,q)$▫-equation) with a singular and ▫$(p-1)$▫-superlinear reaction and a ... Robin boundary condition with ▫$(q-1)$▫-sublinear boundary term ▫$(q<p)$▫. So, the problem has the combined effects of singular, concave and convex terms. We look for positive solutions and prove a bifurcation-type theorem describing the changes in the set of positive solutions as the parameter varies.
