A nonsmooth variational approach to semipositone quasilinear problems in ${\mathbb{R}}^N$

Jefferson Abrantes Santos, Claudianor O. Alves, Eugenio Massa

This paper concerns the existence of a solution for the following class of semipositone quasilinear problems \begin{equation*} \left \{ \begin{array}{rclcl} -Δ_p u = h(x)(f(u)-a),\…
