关于方程X^(n)+[λ+εp(t)]x=q(t)的周期解

ON THE PERIODIC SOLUTION OF THE EQUATON X^(n) + [λ + εp(t)]X = q(t)

本文研究形如x^(n)+[λ+εP(t)]x=q(t)型方程,给出它存在周期解的条件,并讨论了该周期解的唯一性和稳定性。

In this paper, we consider the equationWe give an existence condition of the periodic solution of the equation (* ) and discuss the uniqueness and stability of the periodic solution.
