Abstract
We consider the algebras of Fourier multipliers and show that every bounded continuous function on can be transformed by an appropriate homeomorphic change of variable into a function that belongs to for all , . Moreover, under certain assumptions on a family of continuous functions, one change of variable will suffice for all . A similar result holds for functions on the torus . This may be contrasted with the known result on the Wiener algebra, related to Luzin's rearrangement problem.
