Abstract
We consider the algebras Mp of Fourier multipliers and show that for every bounded continuous function f on Rd there exists a self-homeomorphism h of Rd such that the superposition f∘h is in Mp(Rd) for all p, 1<p<∞. Moreover, under certain assumptions on a family K of continuous functions, one h will suffice for all f∈K. A similar result holds for functions on the torus Td. This may be contrasted with the known solution of Luzin's problem related to the Wiener algebra.
