Multiplicity results for a subcritical Hamiltonian system with concave-convex nonlinearities

Oscar Agudelo, Bernhard Ruf, Carlos Velez

We study the {\it Hamiltonian elliptic system} \begin{eqnarray}\label{HS1-abstract} \left\{ \begin{aligned} -Δu & = λ|v|^{r-1}v +|v|^{p-1}v \qquad &\hbox{in} \ \ Ω,\\ -Δv & = μ|u|^…
