Hamburg Set Theory Workshop 2020

HSTW 2020: Hamburg Set Theory Workshop 2020
Descriptive Set Theory, Forcing and the Reals
Hamburg, Germany
20 & 21 June 2020

https://www.math.uni-hamburg.de/spag/ml/HSTW2020/

== Speakers:
1.       Vera Fischer (Vienna)
2.       Yurii Khomskii (Hamburg & Amsterdam)
3.       Dominique Lecomte (Paris)
4.       Heike Mildenberger (Freiburg)
5.       Dorottya Sziraki (Budapest)
6.       Otmar Spinas (Kiel)
7.       Asger Tornquist (Copenhagen)
8.       Jindrich Zapletal (Gainesville FL)
more TBA.

== Topic:
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.

Ultramath 2020, Pisa

Ultrafilters and Ultraproducts Across Mathematics and Related Topics
May 31 – June 6, 2020, Pisa, Italy

http://people.dm.unipi.it/ultramath2020/

We are happy to announce the upcoming event “ULTRAMATH 2020 – Ultrafilters
and Ultraproducts Across Mathematics and Related Topics”, that will be
held in Pisa (Italy) from May 31st to June 6th 2020.

The international Conference “ULTRAMATH 2020” aims to present recent
results in the whole spectrum of mathematics which are grounded on the use
of ultrafilters and ultraproducts. Its main goals:

• Disseminate information about the various techniques related to the use
  of ultrafilters and ultraproducts, and their potential to attack open
  problems.
• Bring together researchers with different backgrounds, and encourage
  their collaborations and interactions, especially on topics connecting
  different areas of mathematics.

The covered topics of UltraMath 2020 include (but are not limited to):

Additive and Combinatorial Number Theory.
Combinatorics and Ramsey Theory.
Algebra and Geometry.
General Topology.
Measure Theory.
Ergodic Theory and Dynamics.
Functional Analysis and Metric Spaces.
Nonstandard Analysis and Model Theory.
Generalized Spaces and Differential Equations.
Set Theory.

Greater prominence will be given to those results that satisfy (most of)
the following conditions:

• The results can be formulated and presented in non-specialist terms, and
  be in principle understandable by any practicing mathematician.
• The usage of ultrafilters/ultraproducts is important (or even essential)
  in obtaining these results.
• The results connect different areas of mathematics.
• The results reveal new facets of known important topics.

This is the second edition of ?UltraMath?, after the one held in Pisa in
2008: http://people.dm.unipi.it/ultramath.
