ALGOS 2020 – ALgebras, Graphs and Ordered Sets – August 26th to 28th (Online)

The conference ALGOS 2020 ALgebras, Graphs and Ordered Sets will take place online from August 26th to 28th, 2020.

To receive news and further information on the online event, please register.

Originating in arithmetics and logic, the theory of ordered sets is now a field of combinatorics that is intimately linked to graph theory, universal algebra and multiple-valued logic, and that has a wide range of classical applications such as formal calculus, classification, decision aid and social choice.

This international conference « Algebras, graphs and ordered sets » (ALGOS 2020) will bring together some of the best specialists in the theory of graphs, relational structures and ordered sets, themes that are omnipresent in artificial intelligence and in knowledge discovery, and with concrete applications in biomedical sciences, security, social networks and e-learning systems. One of the goals of this event is to provide a common ground for researchers in various fields of computer science and mathematics to meet, present their latest results, and discuss original applications in related scientific fields. On this basis, we hope for fruitful exchanges that can motivate multidisciplinary projects.

ALGOS 2020 is dedicated to Maurice Pouzet on the occasion of his 75th birthday.

Maurice Pouzet is Emeritus Professor of the University Claude-Bernard Lyon 1 and adjunct-professor of the University of Calgary (Canada).

ALGOS 2020 will be on August 26 (Wednesday), 27 (Thursday), 28 (Friday) of 2020, and was planned to take place at the Lorraine Research Laboratory in Computer Science and its Applications (LORIA, UMR 7503). Due to the COVID-19 pandemic, ALGOS 2020 will take place online. To receive news and further information on the online event, please register.

There will be several presentations (keynote/regular). In addition to the local proceedings from LORIA (Université de Lorraine, CNRS, Inria Nancy G.E.), three special journal volumes are have been confirmed in the Journal of Multiple-Valued Logic and Soft-ComputingDiscrete Mathematics & Theoretical Computer Scienceand Order for selected contributions.

2020 Logic Colloquium postponed to 2021

Due to public health concerns regarding COVID-19, the ASL Executive 
Committee, in consultation with the local organizers and the ASL European 
Committee, has made the decision to postpone the 2020 Logic Colloquium. 

It will take place on July 19-24, 2021, approximately a year later than 
originally scheduled, in the same location:  Poznan, Poland. 

The Executive Committee very much regrets having had to make this decision, 
but considers it the only responsible course of action.  Please see the LC 2020 website for further details.

Any questions may be addressed to the ASL Secretary-Treasurers Russell 
Miller and Reed Solomon, and/or the the ASL office, at

We hope to see you in Poznan in 2021!

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

1.       Vera Fischer (Vienna)
2.       Yurii Khomskii (Hamburg & Amsterdam)

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 

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.
