利用Krasnoselskii不动点定理,研究了带Lalacian型算子的三点边值问题正解的存在性,得到其存在正解的充分条件,改进和丰富了以往文献的一些结论.
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.
