摘　　要：By means of nonlinear alternative of Leray-Schauder type and Schauder fixed point theorem, the existence of positive solutions to singular semi-positone nonlinear third-order differential equations are established. The results are illustrated with an example.By means of nonlinear alternative of Leray-Schauder type and Schauder fixed point theorem, the existence of positive solutions to singular semi-positone nonlinear third-order differential equations are established.
