摘要

给出了复系数标量Riccati方程的正解和极解的定义。研究了Riccati方程正解和极值解的一些性质。在此基础上,证明了描述两个线性一阶常微分方程系统解的渐近性的若干定理(特别是证明了两个线性一阶常微分方程系统解的极小性定理)。

Properties of solutions of the scalar Riccati equation with complex coefficients and some their applications
The definition of normal and extremal solutions of the scalar Riccati equation with complex coefficients is given. Some properties of normal and extremal solutions to Riccati equation are studied. On the basis of the obtained, some theorems which describe the asymptotic behavior of solutions of the system of two linear first order ordinary differential equations are proved (in particular a minimality theorem of a solution of the system of two linear first order ordinary differential equations is proved).
