Critical point approaches for impulsive Sturm-Liouville differential equations with nonlinear derivative dependence


Z. Mehraban, S. Heidarkhani




We guarantee the existence of multiple solutions for a class of impulsive Sturm-Liouville differential equations by considering a consequence of Bonanno's local minimum theorem on the nonlinear term and as well as, via critical point theorems due to Bonanno and another one due to Averna and Bonanno in a special case.
