摘要:

该文研究了某类二阶非齐次周期微分方程的次正规解的存在性, 解的增长性及振荡性.同时也研究了由上述方程的解生成的
微分多项式L(f)=d2f''+d1f'+d0f与小函数的关系, 其中d0(z), d1(z), d2(z)为整函数, 不同时为0.

关键词: 期微分方程, 次正规解, 超级

Abstract:

In this paper, the existence of subnormal solution, the growth and the oscillation of solutions of certain second-order nonhomogeneous periodic differential equation are investigated. Also, the relationship between small functions and differential polynomials L(f)=d2f''+d1f'+d0f generated by solutions of the above equation, where d0(z), d1(z), d2(z) are entire functions that are not all equal to zero, is studied.

Key words: Periodic differential equation, Subnormal solution, Hyper-order
