Abstract: | By using well-known Krasnoselskii fixed point theorem,a class of three-point boundary value problem with Laplacian-Like operator is studied,sufficient conditions are obtained to ensure the existence of positive solutions.And the results improve and enrich the conclusions in the literature. |
