微分方程正解的存在唯一性

Existence and uniqueness of positive solution of differential equation

本文利用锥理论和极大值原理在f(t,x)具有特殊形式下,即可以分解为两个函数的乘积时,给出了二阶微分方程Dirichlet边值问题正解的存在唯一性的充分条件。

When ,we use the theory of cone and maximum to give the sufficient condition of the existence and uniqueness of positive solution of second order differential equation with boundary problem.
