| Abstract: | In this paper, we study a fourth-order singular boundary value problem. Using the Leggett-Williams fixed point theorem together with constructing a special cone, we establish optimal existence of symmetric positive solutions for a fourth-order singular boundary value problem under certain conditions, which generalizes optimal existence of symmetric positive solutions to singular boundary value problem. |

| Keywords: | symmetric positive solutions boundary value problem cone |
