On the failure of the H\"ormander multiplier theorem in a limiting case

Classical Analysis and ODEs 2018-05-28 v1

Abstract

We discuss the H\"ormander multiplier theorem for LpL^p boundedness of Fourier multipliers in which the multiplier belongs to a fractional Sobolev space with smoothness ss. We show that this theorem does not hold in the limiting case 1/p1/2=s/n|1/p-1/2|=s/n.
