We investigate in this paper the following second-order multipoint boundary value problem: , , , . Under some conditions, we obtain global structure of positive solution set of this boundary value problem and the behavior of positive solutions with respect to parameter by using global bifurcation method. We also obtain the infinite interval of parameter about the existence of positive solution.
