Positive solutions for singular (p,q)-Laplacian equations with negative perturbation

[摘要] We consider a nonlinear Dirichlet problem driven by the(p,q)-Laplacian and with a reaction consisting of a singular term plus a negative perturbation. Using regularization of the singular term and truncation and comparison techniques, we show that the problem has a unique positive smooth solution.
