About This year we will study effective results in homogeneous dynamics. First we will discuss the general problem of effectivization of results in ergodic theory and discuss by-now classical techniques involving the theory of unitary representations. Then we will turn to the following recent breakthrough papers.
  • Khintchine dichotomy for self-similar measures, by Timothée Bénard, Weikun He and Han Zhang

  • Multislicing and effective equidistribution for random walks on some homogeneous spaces, by Timothée Bénard and Weikun He

  • Effective equidistribution for some one-parameter unipotent flows, by Elon Lindenstrauss, Amir Mohammadi and Zhiren Wang.
