| 摘 要： | 在复域C内研究了一类含有未知函数迭代的二阶微分方程的可逆解析解的存在性.通过变换,把这类方程化为一种不含未知函数迭代的泛函微分方程,并给出了它的局部可逆解析解.讨论了双曲型情形和共振的情形,还在Brjuno条件下讨论了在共振点附近的情形.

| Abstract: | The second-order differential equation involving iterates of the unknown function was studied in the complex field C for the existence of invertible analytic solutions.Through the transformation,this equation is transformed into another functional differential equation without iteration of the unknown function,and give its local invertible analytic solutions.We discuss not only those given in the transformation in the hyperbolic case and resonance,but also those near resonance under Brjuno condition. |
