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. Webvector space containing all the continuous periodic functions, one sees that every element of this vector space satisfies Condition A. If one now completes the space by using the topology of uniform convergence on R, then one gets the linear space of all functions satisfying Condition A. We call this space AP, the space of almost periodic ...
