利用锥上不动点定理,研究了一类非线性二阶三点边值问题正解的存在性,得到了存在正解的几个充分条件.
By ultlizing a fixed point theorem on a cone in Banach space, the existence of positive solutions for a kind of nonlinear second-order three-point boundary value problem is studied in this paper, and several sufficient conditions for the existence of positive solutions are obtained.
