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.en510 Mathematikanisotropic (p, q)-Laplaciansingular termsuperlinear perturbationregularity theorymaximum principlepositive solutionsArticle1988-2807
