2nd and final Announcement:  Please circulate among your students.

Workshop “DMV-Studierendenkolleg: UnDecidability”
29. – 30. June 2018
Hamburg, Germany

There is no participation fee, but registration is required (ideally till 01. June 2018) The number of participants is limited and distributed by a first-come first-served principle! We also offer light meals.

Regula Krapf (U Koblenz-Landau)
Christian Reiher (U Hamburg)
Daniel T. Soukup (U Vienna)

This two days DMV Studierendenkolleg is concerned with the topic of undecidability. In several talks and workshops we will be introduced to the topic and receive an overview, also concerning the intersections with other topics in mathematics (here infinite combinatorics). Finally we will catch a glimpse of today’s scientific borders in two research talks.

The DMV Studierendenkolleg targets students of mathematics or similar subjects. Although the main target audience are bachelor and master students we are looking forward to also welcome interested PhD students or advanced scholars.

Here we would like to sincerely thank our sponsors, who made this event possible! These are the

Dieses zweitägige DMV Studierendenkolleg beschäftigt sich mit dem Thema Unabhängigkeit/Unentscheidbarkeit. In mehreren Vorträgen und Workshops erhalten wir eine Einführung in und einen Überblick über das Thema sowie seine Berührungspunkte mit anderen Teilen der Mathematik, hier exemplarisch unendliche Kombinatorik. Final wenden wir uns in Forschungsvorträgen dem aktuellen Stand der Wissenschaft zu.

Das DMV Studierendenkolleg richtet sich an Studierende der Mathematik und verwandter Fächer. Wir uns aber ebenfalls Doktorranden und Wissenschaftler begrüßen zu dürfen.

Wir möchten uns an dieser Stelle herzlich bei unseren Sponsoren bedanken, die diese Veranstaltung ermöglichen!

Masterclass on Generalised Baire Spaces, Amsterdam

on Generalised Baire Spaces
22 August 2018 at the
Koninklijke Nederlandse Akademie van Wetenschappen KNAW
Het Trippenhuis, Amsterdam, The Netherlands
(with KNAW Academy Colloquium on 23 and 24 August 2018)

In combination with the KNAW Academy Colloquium “Generalised Baire Spaces”, the Royal Netherlands Academy of Arts and Sciences is offering a one day Master Class on the topic of Generalised Baire Spaces. In classical descriptive set theory, Baire space is the most central topological space for the study of the real numbers, consisting of functions from omega to omega. Moving from omega to an uncountable cardinal kappa, one can consider *generalised Baire spaces*, the sets of functions from kappa to kappa. The study of these spaces has become a very important subject in set theory in the past decade.

The KNAW Academy Colloquium on Generalised Baire Spaces on 23 and 24 August is a meeting of the researchers of this field, exchanging the latest research results.

On the 22nd of August, we are organising a Master Class with four 2-hour courses taught by Andreas Blass, Jouko Vaananen, Andrew Brooke-Taylor, and Philipp Schlicht. This Master Class will teach the basic material needed to understand the research results discussed during the colloquium on the two following days. The following are the titles of the four classes:

Andreas BLASS. The classical theory of cardinal invariants.
Jouko VAANANEN. Generalized Baire spaces–basic concepts and motivation.
Andrew BROOKE-TAYLOR. Generalising the weak compactness of omega.
Philipp SCHLICHT. Descriptive set theory in the setting of generalized
Baire spaces.

We invite all graduate students in logic to participate in the Master class. Registration for the Master class is free, but we cannot provide any support for travel expenses and/or accommodation in Amsterdam. Space permitting, participants of the Master class are allowed to attend the colloquium lectures on the two following days.

In order to participate in the Master class, please register by sending an e-mail to Lorenzo Galeotti at


before the deadline of 15 June 2018. This e-mail should contain

(a) your name and e-mail address,
(b) your current graduate student status (including your university),
(c) name and contact details of your supervisor, and
(d) a brief (one paragraph) explanation why you’re interested in
the topic.

Accessible categories and their connections, Leeds

Accessible categories and their connections
– set theory – model theory – homotopy theory –

17-20 July 2018, University of Leeds

Accessible categories are notable for their importance in other areas of mathematics, be it through combinatorial model categories in homotopy theory or abstract elementary classes in model theory, with large cardinal axioms from set theory often thrown into the mix.  The goal of this workshop is to bring together practitioners from these different fields to try to break down barriers and build new connections.


There is no registration fee, but those wishing to attend should email with “Accessible categories registration” in the subject line and their name and affiliation in the message body to register.  Those wishing to offer a contributed talk should send their title and abstract by June 11th.
