| Abstract: | We study backward uniqueness properties for equations of the form   and  , it is shown that  implies  for  . The argument is based on  -log and log-log convexity. The results apply to mildly nonlinear parabolic equations and systems with rough coefficients and the 2D Navier-Stokes system. |
