A note on characterized and statistically characterized subgroups of ๐ = โ/โค
Abstract Recently, P. Das, A. Ghosh and T. Aziz have given a criterion for statistically characterized subgroups of the circle group โ/โค to be torsion. Here we give a completely different and much shorter proof of this result. Moreover, we give for a characterized subgroup of โ/โค a sufficient condition to be torsion, unifying and generalizing earlier results.
