Abstract
Concerning iterative roots, a main difficulty comes from forts of continuous functions. A case of infinitely many forts is the class of functions with plateaus. In this paper we consider functions in this class and their iterative roots. We discuss on changes of plateaus under iteration and give a criterion to determine the clenched class. Then we find all iterative roots for clenched single-plateau functions.
