摘要 在复数域中讨论二阶迭代函数方程的解析解。对Schrder变换中的常数α,主要讨论α是共振点,即α是单位根的情形以及α在共振点附近且满足Brjuno条件的情形。 Analytic solutions of an second-order iterative functional equation are discussed in a complex field.For the constant α given in the transformation,we discuss those α is at resonance,i.e.at a root of the unity and those α near resonance under the Brjuno condition.
