We consider a nonlinear anisotropic Dirichlet problem with reaction that has the combined effects of three distinct nonlinearities: parametric singular term, "concave" term (the parameter \begin{document}$ \lambda>0 $\end{document} is same in both) and nonparametric "convex" perturbation. So, version w...
