We consider a Dirichlet problem driven by the anisotropic (p, q)-Laplacian and with a reaction that has the competing effects of a singular term and of a parametric superlinear perturbation. Based on variational tools along with truncation and comparison techniques, we prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter varies.

关于一类奇异各向异性（p，q）方程

我们考虑由各向异性（p，  q）-Laplacian驱动的Dirichlet问题，其反应具有奇异项和参数超线性摄动的竞争效应。基于变分工具以及截断和比较技术，我们证明了分叉类型的结果，该结果描述了随着参数变化而导致的正解集的变化。
