DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CJCS/41/">Ra
 nk of matrices with entries from a multiplicative group</a>\nby Jozsef Sol
 ymosi (University of British Columbia) as part of Copenhagen-Jerusalem Com
 binatorics Seminar\n\n\nAbstract\nWe establish lower bounds on the rank of
  matrices in which all but the diagonal entries lie in a multiplicative gr
 oup of small rank. Applying these bounds we show that the distance sets of
  finite pointsets in ℝ^d generate high rank multiplicative groups and th
 at multiplicative groups of small rank cannot contain large sumsets. (Join
