Positive solutions for singular (p,q)-Laplacian equations with negative perturbation. <i>Electronic Journal of Differential Equations, 2023</i>(25), pp. 1-9.1072-6691https://hdl.handle.net/10877/16860We 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.Text9 pages1 file (.pdf)enAttribution 4.0 International(p,q)-LaplacianSingular termNegative perturbationNonlinear regularityRegularized singular termArticle
