Positive Solutions of Sturm-Liouville Boundary Value Problems in Presence of Upper and Lower Solutions
2011
International Journal of Differential Equations
We consider a kind of Sturm-Liouville boundary value problems. Using variational techniques combined with the methods of upper-lower solutions, the existence of at least one positive solution is established. Moreover, the upper solution and the lower solution are presented.
