On geometric complexity of Julia sets - III

26.09.2021 - 01.10.2021 | Będlewo & Online (hybrid)

We hope this will be a hybrid conference. For those who cannot attend the conference in person, online participation will be possible.

The conference addresses a question of how complex Julia sets can be. This topic is of a great importance in modern dynamical systems. It includes (but is not limited to):

  • Hausdorff dimension and Lebesgue measure,
  • connectivity, local connectivity and porosity,
  • computability and computational complexity,
  • accessibility from infinity of points of Julia sets
    of both rational maps and transcendental functions.

Many established specialists in complex dynamics, including  Artur Avila, Krzysztof Barański, Xavier Buff, Arnoud Chéritat, Núria Fagella, Hiroyuki Inou, Bogusława Karpińska, Genadi Levin, Mikhail Lyubich, Mitsuhiro Shishikura, Grzegorz Świątek  and  Anna Zdunik  studied geometric complexity of Julia sets and obtained prominent results. However, many problems remain wide open. We hope that during the planned conference fruitful discussions will emerge, new techniques will be discussed and new collaborations will start.
