摘要

This paper is concerned with a first order iterative functional differential equation of the form x'(z) = f(x(p(z) + bx(z))). By constructing a convergent power series solution of an auxiliary equation of the form beta y'(beta z) - p'(y(z)) y'(z) = by'(z) f[1/b(y(beta(2)z) - p(y(beta z)))], analytic solutions of the form x(z) = 1/b [y(beta y(-1)(z)) - p(z)] for the original equation are obtained.
