This article concerns the first-order functional differential equation $$ x'(z)=x(p(z)+bx'(z)) $$ with the distinctive feature that the argument of the unknown function depends on the state derivative. An existence theorem is established for analytic solutions and systematic methods for deriving explicit solutions are also given.


... In 1993, Fečkan showed the existence of local solutions via the Contraction Mapping Principle for the initial value problem for the iterative differential equation x (t) = f (x(x(t))), x(0) = 0. For more on iterative differential equations see the papers [1,2] [5]- [8], [11]- [14] and references therein. ...
