摘要:

We consider a parametric Dirichlet problem driven by the p-Laplacian with a Carath´eodory reaction of equidiffusive type. Our hypotheses incorporate as a special case the equidiffusive p-logistic equation. We show that if λ1 > 0 is the principal eigenvalue of the Dirichlet negative p-Laplacian and λ > λ1 (λ being the parameter), the problem has a unique positive solution, while for λ ∈(0, λ1], the problem has no positive solution.

关键词: p-Laplacian, p-logistic equation, first eigenvalue, equidiffusive reaction, maxi-mum principle, nonlinear regularity
