DESCRIPTION:Georgi Dvali (LMU & NYU)\nAny de Sitter patch that lasts longe
 r than a certain critical number of Hubble times suffers an effect of  q
 uantum breaking. \nThe requirement that this must not happen puts severe
  constraints on the scalar potentials.  In particular\, it eliminates bot
 h local and global minima with positive energy densities as well as suppre
 sses the  inflationary  regimes  with  self-reproduction and eter
 nity.  An obvious prediction  of quantum breaking bound is that today'
 s dark  energy cannot be constant. We shall explain the above and discu
 ss some implications for inflationary models in quantum field theory and i
 n D-branes.
