Abstract: The periodic boundary value problems for nonlinear functional differential equations was discussed. The existence of maximal and minimal solutions was obtained when the lower and upper solutions satisfied the formal or reverse order.

Key words: periodic boundary value problem, monotone iterative technique, maximal and
minimal solutions
