DESCRIPTION:Featured Speaker :  Alex Cohen (MIT Mathematics)\n\nTitle :  A 
 discrete 2D fractal uncertainty principle\n\nAbstract : A fractal uncertai
 nty principle (FUP) states that a function `f' and its Fourier transform c
 annot both be large on a fractal set. These were recently introduced by Se
 myon Dyatlov and collaborators in order to prove new results in quantum ch
 aos. So far FUPs are only understood for fractal sets in R\, and fractal s
 ets in $R^2$ remain elusive. In this talk\, we prove a sharp fractal uncer
 tainty principle for Cantor sets in Z/NZ x Z/NZ\, a discrete model for $R^
 2$.
