The workshop will focus on recent developments in the study of the topological, measure-theoretic, and geometric properties of achievement sets. Our aim is to bring together researchers working on achievement sets to discuss and work on old and new problems in this area. The main topic of this workshop issue is the centre of distances, its properties and applications to achievement sets.

Our workshops are a cyclic event, which started in May 2021 in Będlewo (as a research group), the 2nd workshop took place at the Łódź University in November 2021, the 3rd and 4th workshops were hosted by the Szczecin University in February 2022 and February 2023. The last edition was held in Będlewo in November 2023.
