Abstract: Let , and , be nonnegative functions. Sufficient conditions are found in order that for all . Pointwise and norm approximations of are derived. Similar results are obtained when is replaced by a measure weight. In the case , a counterexample is given which shows that no Fourier inequality can hold for all in . Spherical restriction theorems are established. Further conditions for the boundedness of are discussed.
