DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/IMS/4
 /">Regularity estimates for the flow of BV autonomous divergence-free plan
 ar vector fields</a>\nby Elio Marconi (University of Basel) as part of PDE
  seminar via Zoom\n\n\nAbstract\nWe consider the appropriate notion of flo
 w $X$ associated to a bounded divergence-free vector field $b$ with bounde
 d variation in the plane. We prove a Lusin-Lipschitz regularity result for
  $X$ and we show that the Lipschitz constant grows at most linearly in tim
 e. As a consequence we deduce that both geometric and analytical mixing ha
 ve a lower bound of order $1/t$ as $t\\to \\infty$. This is a joint work w
 ith Paolo Bonicatto.\n
