一类二阶奇异微分方程解的最大存在区间

The Largest Existentially Definable Interval of a Class of Second Order Singular Differential Equations

本论文研究一类二阶奇异微分方程解的最大存在区间问题。第一部分我们叙述了研究常微分方程解的存在性的意义,一些重要的常微分方程解的存在定理以及解的最大存在区间定理。第二部分我们研究了一类二阶奇异微分方程的解的最大存在区间。

In this thesis, we investigate the largest existentially definable interval for the solutions of a class of second order singular differential equations. In the first part, we show the meaning for studying the existence of solutions of ordinary differential equations, some important existence theorems and the largest existentially definable interval theorems for solutions. In the second part, we study the largest existentially definable interval of a class of second order singular differential equations.
