Abstract:

It is shown that a Schur multiplier is compact if and only if it is the Schur product of two multipliers, one of which is a Hankel–Schur multiplier generated by an integrable function. This is illuminated by factoring exotic, singular measures and is brought into relation with Paley set-based multipliers.
