In [[mathematical analysis]], '''constructive function theory''' is a field which studies the connection between the smoothness of a [[Function (mathematics)|function]] and its degree of [[approximation theory|approximation]]<ref>{{cite web|url=http://encyclopedia2.thefreedictionary.com/Constructive+Theory+of+Functions|title=Constructive Theory of Functions}}</ref><ref>{{SpringerEOM|id=c/c025430Constructive_theory_of_functions|title=Constructive theory of functions|first=S.A.|last=Telyakovskii}}</ref>. It is closely related to [[approximation theory]]. The term was coined by [[Sergei Bernstein]].
