摘要
The aim of this paper is to study a parameter-dependent nonlinear differential problem with Sturm-Liouville type equation and Dirichlet boundary conditions. In particular, by requiring a suitable behavior on the nonlinearity, we determine an interval of parameter lambda for which the problem admits three or infinitely many solutions.
