Nonlinear singular problems with gradient dependence
摘要
We consider a Dirichlet problem driven by a nonlinear nonhomogeneous differential operator, with a reaction which exhibits the combined effects of a parametric singular term and of a Carathéodory gradient dependent perturbation. Using the theory of nonlinear operators of monotone type, we show that for all small values of the parameter the problem has at least one positive smooth solution.
