Abstract: Abstract: In this paper, we consider the existence and uniqueness positive solutions of the boundary Neumann problem. We show that under rather general conditions on the coefficients and more general nonlinearity, the above problems possesses a minimal positive solution and a maximal positive solution, respectively, Moreover, we first establish a relationship between the above problem and the problem in whole space. We obtain a comparison principal which our proof of the existence results rely essentially on. and make use of a rather intuitive squeezing method to get the existence theorems. Furthermore, by analyzing the behavior of the positive solution for the problem in whole space, we show the boundary Neumann problem in half space has only one positive solution. Our results improve the previous works.
