摘要:

研究一类具有积分边界条件的二阶非线性常微分方程非局部边值问题多个正解的存在性. 利用双锥上不动点定理, 在允许非线性项变号的情况下, 得到了边值问题至少存在两个正解的充分条件.

关键词: 积分边值问题; 双锥上不动点定理; 正解; 存在性

Abstract:

We studied the existence of multiple positive solutions for the nonlocal boundary value problems of a type of nonlinear second order differential equations with integral boundary conditions. By means of fixedpoint theorem in double cones, the existence of, at least, two positive solutions to the boundary value problem is obtained under the condition of nonlinear term to be allowed to change sign.

Key words: integral boundary value problem, a fixedpoint theorem in double cones; positive solutions; existence
