Abstract
In the space of continuous functions defined on a simple continuous contour, we examine the functional equationa(t)ϕ(t)+b(t)ϕ[ϕ(t)]=g(t)
A criterion for Eq. (1) being Noetherian is established under the condition that there exist a finite number of fixed points on the first multiplicity in the homeomorphism α(t) of the contour onto itself.
