Abstract
We give a sufficient condition for a smooth not necessarily injective function Ï:RâR ensuring that the composition operator CÏ:Câ(R)âCâ(R), Fâ¦FâÏ has closed range. This generalizes in a special case the result of Kenessey and Wengenroth which gave a description of composition operators CÏ with closed range for smooth injective symbols Ï:RâRd.
