Hierarchy of almost-periodic function spaces

WebEvery Weyl almost periodic function is Besicovitch almost periodic, and therefore Theorem 5 provides a counterexample to Theorem 2 with the class of almost periodic distributions replaced by the classes of Weyl and Besicovitch almost periodic functions [taking y = 0, we get D(u) = /«/; this function is invertible for every w T 0]. 3.
