摘要/Abstract

摘要：

研究了有理系数的差分Riccati方程和常系数的时滞微分方程.当系数满足一定关系时，证明了差分Riccati方程的超越亚纯解具有不小于1的增长级.对于常系数的时滞微分方程，讨论了有理解在z → ∞时的渐近行为.

关键词: 差分Riccati方程, 亚纯解, 时滞微分方程, 有理解

Abstract:

We investigate difference Riccati equations with rational coefficients and delay differential equations with constant coefficients. For difference Riccati equations with some relation among coefficients, we prove that every transcendental meromorphic solution is of order no less than one. We also consider the rational solutions for delay differential equations.

Key words: Difference Riccati equation, Meromorphic solution, Delay differential equation, Rational solution
