Abstract: Analytic solutions of a secondorder iterative functional differential equation x″(x[r](z))=c0z+c1x(z)+…+cmx[m](z), z∈C, were discussed in a complex field, where r and m are nonnegative integers, c0,c1,…,cm are complex constants, and x[i] is the ith iterated function x(z). The analytic solutions are obtained in the case of unit root α, of which that the linearized eigenvalue α is near resonance under the Brjuno condition.
Key words: majorant series , analytic solution, functional differential equation, iteration
