Abstract

We giv;…ufficient and necessary condition fo;…unction with its values in the unit circle to b;…ultiplicative coboundary. This theorem generalizes the following result of Veech [1]. Let T;…#x2192;……otation of the unit circl;…y an irrational angle θ. Let F;…#x2192;……easuable function. The;……ultiplicative coboundary iff ∫T F(x)F(Tx) ……Tn-1x)dμ(x) → 1, as ||nθ|| → θ where ||no|| is the distance of no from integers an;…s the Haar measure.
