On a Robin (p,q)-equation with a logistic reaction

We consider a nonlinear animed blue lotion topical spray 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 bostik mvp solutions as the parameter (lambda gt 0) varies.Also, we show that for every admissible parameter (lambda gt 0), the problem admits a smallest positive solution.
