| Abstract: | This paper is concerned with the existence of bifurcation points and global structure of positive eigenvalues for the nonlinear cone mappings in the ordered Banach spaces. The difference from the existing results is that the operators are not assumed to be Frechet differentiable at the zero point along the cone. As an application, the existence of at least one bifurcation point and global structure of positive solutions for the boundary value problems of nonlinear elliptic partial differential equations are discussed. |
