On the extremal parameters curve of a quasilinear elliptic system of differential equations

  • Kaye SilvaEmail author

We consider a system of quasilinear elliptic equations, with indefinite super-linear nonlinearity, depending on two real parameters \(\lambda ,\mu \). By using the Nehari manifold and the notion of extremal parameter, we extend some results concerning existence of positive solutions.
