# Integrability of trigonometric series with generalized semi-convex coefficients

Abstract. In this paper we deal with cosine and sine trigonometric series with generalized semi-convex coefficients. Integrability conditions for them are obtained.
Keywords: trigonometric series, generalized semi-convex sequences.
