| Abstract: | The positive solutions to a class of higher order singular boundary value problems are studied.By a proper transformation of this problem,the sufficient condition for the existence and uniqueness of positive solution to this class of singular boundary value problems was gained by using the fixed point theorems for u0 concave operators in the case that the nonlinear term satisfies some conditions. |

| Keywords: | positive solution boundary value problem u0 concave operators uniqueness |
