A classical result of Norbert Wiener characterises doubly shiftinvariant subspaces for square integrable functions on the unit circle with respect to a finite positive Borel measure µ, as being the ranges of the multiplication maps corresponding to the characteristic functions of µ-measurable subsets of the unit circle. An analogue of this result is given for the Besicovitch Hilbert space of ‘square integrable almost periodic functions’.
