Title: Non-trivial solutions for two-point boundary-value problems of
       fourth-order Sturm-Liouville type equations

Author: Shapour Heidarkhani (Razi Univ., Kermanshah, Iran)

Abstract:
 Using critical point theory due to Bonanno [3], we prove the
 existence of at least one non-trivial solution for a class of
 two-point boundary-value problems for fourth-order Sturm-Liouville 
 type equations.
