| Abstract: | In this paper,the number of solutions to a second-order Neumann boundary value problem with singular nonlinearity are concerned. Comparison theorem,maximum principle and upper solutions method are employed to come to a conclusion that,in some condition,the number of solutions for this problem is exactly five. |
