DESCRIPTION:In this talk we will discuss some situations in wh
 ich a Fourier inequality (including the classical 
 Hausdorff-Young and Hardy-Littlewood estimates) ca
 n be extended to a broader class of operators. We 
 will also see how this can be used to solve two cl
 assical problems: the Bernstein problem of absolut
 e convergence of Fourier series and the characteri
 zation of Fourier inequalities with monotonic weig
 hts.
