Abstract
LetG be any connected compact group with dual objectĜ. We give in this paper a new proof that the union of any two Sidon sets inĜ is again a Sidon set. We also show that any Sidon subset ofĜ is the union of a set whose elements have bounded degree with a finite union of sets which satisfy a quasi-independence condition.
