We consider a nonlinear elliptic Dirichlet problem driven by the anisotropic (p, q)-Laplacian and with a reaction which is nonparametric and has the combined effects of a singular and of a superlinear terms. Using variational tools together with truncation and comparison techniques, we show that the problem has at least two positive smooth solutions.

我们考虑由各向异性(p, q)-Laplacian驱动的非线性椭圆Dirichlet问题,其反应是非参数的,并且具有奇异项和超线性项的组合效应。使用变分工具以及截断和比较技术,我们证明该问题至少具有两个肯定的光滑解。
