DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BODS/11/">Co
 arse-graining of transport in non-autonomous systems</a>\nby Péter Koltai
  (FU Berlin) as part of Bremen Online Dynamics Seminar\n\n\nAbstract\nThe 
 decomposition of the state space of a dynamical system into almost\ninvari
 ant sets is important for understanding its essential macroscopic\nbehavio
 r. The concept is reasonably well understood for autonomous\ndynamical sys
 tems\, and recently a generalization appeared for\nnon-autonomous systems:
  coherent sets. Aiming at a unified theory\, in\nthis talk we will first p
 resent connections between the\nmeasure-theoretic autonomous and non-auton
 omous concepts. We shall do\nthis by considering the augmented state space
 . Second\, we will extend\nthe framework to finite-time systems\, and show
  that it is especially\nwell-suited for manipulating the mixing properties
  of the dynamics.\nThird\, we will show how this framework can be used to 
 identify the birth\nand death of coherent sets.\n
