Abstract: Suppose that the Hausdorff topological group is either compact or locally compact abelian and that denotes the set of continuous complex-valued functions on with compact supports. Let denote the restrictions to of the continuous linear operators from into which commute with all the right translation operators.

When or it is known that

When is compact, simple relations will also be developed between idempotent operators in and lacunary subsets of the dual of which will enable us to find necessary conditions so that inclusion (1) is strict even if, for example, and are replaced by the sets of idempotent operators in and respectively.
