Radial Schur multipliers on trees and the failure of Fourier-Schur transference

Adrian González-Pérez, Javier Parcet, Jorge Pérez García +1

Given $1<p<\infty$ and a function $m:{\mathbf{N}}_0\to \mathbf{C}$, we provide a characterization of radial Schur multipliers $M(x,y)=m(d(x,y))$ on the Schatten $p$-cla…
