  • Nonlinear nonhomogeneous Robin problems with almost critical and partially concave reaction
    Papageorgiou, Nikolaos, 1958- ; Repovš, Dušan, 1954- ; Vetro, Calogero
    We consider a nonlinear Robin problem driven by a nonhomogeneous differential operator, with reaction which exhibits the competition of two Carathéodory terms. One is parametric, ▫$(p-1)$▫-sublinear ... with a partially concave nonlinearity near zero. The other is ▫$(p-1)$▫-superlinear and has almost critical growth. Exploiting the special geometry of the problem, we prove a bifurcation-type result, describing the changes in the set of positive solutions as the parameter ▫$\lambda > 0$▫ varies.
