DESCRIPTION:Title: A geometric stability result for Riesz-potentials\n	Abstr
 act: Riesz' rearrangement inequality implies that integral functionals (su
 ch as the Coulomb energy of a charge distribution) that are defined by a p
 air interaction potential (such as the Newton potential) which decreases w
 ith distance are maximized (under appropriate constraints) only by densiti
 es that are radially decreasing about some point. I will describe recent a
 nd ongoing work with Greg Chambers on the stability of this inequality for
  the special case of the Riesz-potentials in n dimensions (given by the ke
 rnels |x-y|^-(n-s))\, for densities that are uniform on a set of given vol
 ume. For 1< s < n\, we bound the square of the symmetric difference of a s
 et from a ball by the difference in energy of the corresponding uniform di
 stribution from that of the ball.\n
