Abstract
Most known results on global solutions for leading coefficient problem of polynomial-like iterative equations depend on the local linearity of the known functions. In this paper, global C 0 solutions without this assumption is considered. By virtue of Schröder transformation, we give a general construction of infinitely many increasing C 0 solutions for a general form of iterative equation.
