On Weighted Analogs of Wiener’s and Levy’s Theorems for Fourier – Vilenkin Series

In this paper we find the general form of complex homomorphism for some subalgebras of absolutely convergent Fourier – Vilenkin series algebra. As a corollary, we obtain weighted analogs of Wiener’s and Levy’s theorems for Fourier – Vilenkin series.
