### Unbounded connected component of the positive solutions set of some semi-positone problems

#### Abstract

In this paper, first we obtain some

results for structure of positive solutions set of some nonlinear

operator equation. Then using these results, we obtain some

existence results for positive solutions of the nonlinear operator

equation. The method to show our main results is the global

bifurcation theory.
