Quasilinear elliptic systems with convex-concave singular terms and \(\Phi\)-Laplacian operator. (English) Zbl 1413.35162

The authors prove the existence of positive solutions for an elliptic system driven by \(\Phi\)-Laplacian operators and exhibiting singular terms. The proofs rely on regularization and Galerkin approximation.
