Hamburg Set Theory Workshop 2020

Descriptive Set Theory, Forcing and the Reals.
20 & 21 June 2020
Hamburg, Germany Online via Zoom

The Hamburg Set Theory Workshop 2020 is organised by the Arbeitsbereich Mathematische Logik und interdisziplinäre Anwendungen der Logik. It stands in the tradition of the previous workshops HSTW 2014 and HSTW 2016. Everyone is cordially invited to attend.

List of speakers


Although registration is required for all participants, there is no registration fee for this conference. For registration, write to with your name, affiliation (if applicable). Please do this as soon as possible as places are limited. After registration, you will receive a link to the Zoom webinar and Google doc where we plan for smaller Zoom calls simulating coffee breaks and other features involving social interaction.


Descriptive set theory discusses the relationship between logical complexity and good behaviour of sets, so-called regularity properties (e.g. Lebesgue measurability, perfect set property, etc.). It is well known that these properties are closely connected to forcing (and in some cases, large cardinals). Modern developments in set theory such as forcing, large cardinals and determinacy give powerful techniques to tackle problems in descriptive set theory. In recent years, set theorists have generalised classical results of descriptive set theory to generalised reals.
