Existence of positive solutions for fourth-order nonlinear differential systems

CHEN Li-zhen,LI Gang(Sch of Math Sci,Yangzhou Univ,Yangzhou 225002,China)  
The existence of positive solutions for a class of fourthorder nonlinear differential systems with Dirichlet boundary value condition is discussed.By using the Krasnoselskii fixed point theorem,an existence result of two positive solutions is obtained under suplinear condition and sublinear condition.
