We prove that there exists $0<\overline{\mu}<\mu_1(\Omega)$ such that, for each $0<\mu<\overline{\mu}$, the problem has at least $\cat_{\Omega}(\Omega)$ solutions.}, number={2}, journal={Topological Methods in Nonlinear Analysis}, author={Melo, Jessyca Lange Fereira and dos Santos, Ederson Moreira}, year={2015}, month={Jun.}, pages={551–574} }
