Abstract

In this article we calculate the exact location in the Borel hierarchy of UCF, the set of all continuous functions on the unit circle with uniformly convergent Fourier series. It turns out to be complete F_σδ. Also we prove that any G_δσ set that includes UCF must contain a continuous function with divergent Fourier series.
