a b s t r a c t
In this paper, we investigate the existence of triple positive solutions for nonlinear differential equations boundary value problems with increasing homeomorphism and positive homomorphism operator. By using fixed point theorems in cones, we establish results on the existence of three positive solutions with suitable growth conditions imposed on the nonlinear term. As applications, two examples are given to demonstrate our result. The conclusions in this paper essentially extend and improve the known results.

We determine a Green's function for the singular three-point third-order BVP and then we apply the classical Krasnosel'skiΘ's fixed point theorem on an also new cone. The emphasis is mainly that although this BVP does not admit a positive Green's function, the solution obtained is still positive. I
