摘要
在借助于非负矩阵获得正解的先验估计的基础上,用不动点指数理论研究二阶非线性常微分方程组积分边值问题正解和多重正解的存在性.
Based on a priori estimates achieved by utilizing nonnegative matrices, and by using the fixed point index theory, the existence and multiplicity of positive solutions for a system of nonlinear second-order ordinary differential equations with integral boundary conditions are satisfied.
