چکیده
|
Recently, a lot of attention has been given to the study of multi points boundary value problems. this paper is mainly concerned with the existence of positive solutions for a class of nonlinear boundary value problems. we obtain at least one positive solution to this problem. we introduce a completely continuous operator such that, the fixed points of this operator are positive soultions of the problem. we establish some theorems to prove the existence of solutions for this system. a completely continuous operator is defined and by using the fixed point theorem in cones, the existence of solutions is proved.
