DESCRIPTION:Speakers: Stefanos Lappas (Mathematical Institute\, University
  of Bonn)\n\nWe present a weighted Riesz–Kolmogorov criterion for relati
 vely compact sets in variable Lebesgue spaces $L^{p(\\cdot)}(w)$. Using th
 is criterion\, we prove a multilinear extrapolation principle for compactn
 ess. More precisely\, we show that if an $m$-linear operator is bounded on
  weighted variable Lebesgue spaces for all multilinear variable Muckenhoup
 t weights and compact for a single choice of exponents and weights\, then 
 it is compact for all admissible variable exponents and weights. As applic
 ations\, we obtain new compactness results for commutators of multilinear 
 $\\omega$-Calderón–Zygmund operators\, multilinear fractional integrals
  and multilinear Fourier multipliers. This talk is based on joint work wit
