Generalised Baire Spaces, Amsterdam, August 22-24, 2018

KNAW Academy Colloquium

Generalised Baire Spaces

Amsterdam, The Netherlands

Master Class: 22 August 2018 / Colloquium: 23–24 August 2018

Organisers. Lorenzo Galeotti, Benedikt Löwe, Philipp Lücke.
Descriptive set theory and set theory of the reals traditional deal with well-known and well-studied topological spaces such as the real numbers, Cantor space, and Baire space. In recent years, set theorists are increasingly interested in the uncountable analogues 2κ of the Cantor space (generalised Cantor space) and κκ of the Baire space (generalised Baire space) for uncountable cardinals κ.

While many concepts from the classical setting can be transferred to generalised Baire space and some classical results remain true at uncountable cardinals, in general the rich combinatorial nature of uncountable cardinals causes the theory of the corresponding spaces to differ significantly e.g., notions which are equivalent in the classical setting can lead to different notions in the generalised theory. Phenomena like this shed light on structures and properties otherwise hidden in the classical setting.

The study of generalised Baire spaces has developed into a research area in its own right with a rich overarching theory, internally motivated open questions (cf. Khomskii, Laguzzi, Löwe, Sharankou 2016) and an active research community, combining methods and techniques from several branches of set theory like uncountable combinatorics, forcing, large cardinals, inner models and classical descriptive set theory and also involves techniques from classical model theory. The community met first at the Amsterdam Set Theory Workshop 2014 in November 2014, then at a satellite workshop to the German mathematics congress in Hamburg in September 2015, and finally at a workshop at the Hausdorff Center for Mathematics in Bonn in September 2016. This Academy Colloquium is a reunion of the community after a hiatus of two years.

The Colloquium will be preceded by an associated KNAW Master Class for postgraduate students in order to prepare them for the talks at the Colloquium. The KNAW Master Class will take place on 22 August 2018.

First Girona inner model theory conference, Girona, July 16-27 2018

The first Girona inner model theory conference will take place on July 16-27 at the Philosophy Department of the University of Girona, Catalonia.

The conference is a sequel to previous conferences on inner model theory in Münster, Palo Alto, Berkeley and Irvine. Once more, the meeting will draw together researchers and advanced students with an interest in inner model theory, in order to communicate and further explore recent work. There will be courses and single talks Monday-Friday, with 2 1/2 hours of lectures in the morning and 2 1/2 hours of lectures in the afternoon. This will leave ample time for problem sessions, informal seminars, and other interactions.

The conference is organized by Ralf Schindler (Münster), John Steel (Berkeley) and Joan Vergés (Girona). Please contact Ralf Schindler ( if you intend to participate.

11th Young Set Theory Workshop, Lausanne, June 25–29, 2018

The aims of the Young Set Theory workshops are to bring together young researchers in the domain of set theory and give them the opportunity to learn from each other and from experts in a friendly environment. A long-term objective of this series of workshops is to create and maintain a network of young set theorists and senior researchers, so as to establish working contacts and help disseminate knowledge in the field.

This year’s Young Set Theory Workshop will take place at the Bernoulli Center in Lausanne, Switzerland, at the end of the Descpriptive set theory and Polish groups semester. While the organization of the workshop is independent of that of the semester, we hope the proximity will promote attendance of young researchers from extra-European countries.

  • Assaf Rinot (Bar-Ilan University)
  • Christian Rosendal (University of Illinois at Chicago)
  • Dima Sinapova (University of Illinois at Chicago)
