A note on characterized and statistically characterized subgroups of T=R/Z
Abstract
P. Das, A. Ghosh and T. Aziz has given in [Theorem 3.15]ADG a result on statistically characterized subgroups of the circle group R/Z, which answers, together with [Corollary 2.4]DG24, questions of DDB and DG25. Here we give a completely different and much shorter proof of these results.
