András Hajnal (May 13, 1931 — July 30, 2016)

We are sad to report that András Hajnal, one of the Honorary Presidents of the European Set Theory Society, very unexpectedly died on 30 July 2016 after having a heart attack.

He started his work in axiomatic set theory, in fact he was the first to introduce and study relative constructibility, extending the work of Gödel. However, he is more widely known for his ground breaking work in combinatorial set theory, as one of the founders, in collaboration with Erdős and Rado, of the theory of set mappings and, most of all, the partition calculus. His celebrated joint result with Galvin on cardinal exponentiation initiated Shelah to create PCF theory. He also published more than 30 papers on set theoretic topology and so played an essential role in the introduction of the tools and methods of modern set theory to problems of general topology.

In addition to his work in set theory, he has made significant contributions to finite combinatorics as well. Perhaps the best known of these is the Hajnal–Szemerédi theorem on equitable coloring of graphs that proved a conjecture of Erdős.

Solomon Feferman (December 13, 1928 — July 26, 2016)

We are sad to report that Solomon Feferman died on 26 July 2016 following a stroke. Sol is widely known among mathematicians, philosophers, and computer scientists for his contributions to many areas in mathematical logic and the philosophy of logic and mathematics. He provided the foundations for generalizations of the Gödel incompleteness theorems and the arithmetization and formalisation of metamathematics in general. He shaped modern proof theory; in particular in ordinal analysis he determined the proof-theoretic ordinal of the predicative subsystem, known as the Schütte–Feferman ordinal. Building on earlier work by Turing, he proved results on iterated additions of proof-theoretic reflection principles to arithmetic. Sol’s work on axiomatic theories of truth and, in particular, the Kripke-Feferman system has been highly influential.

10-12 September 2016, Hamburg, Germany

Please note that there is only one week left until the deadline for submission of abstracts. If you want to give a talk at the LOGIC COLLOQUIUM 2016, please submit it as soon as possible via .

Submission deadline: 20 June, 2016

The Colloquium Logicum is organized every two years by the “Deutsche Vereinigung für Mathematische Logik und für Grundlagenforschung der Exakten Wissenschaften” (DVMLG).

In 2016 the colloquium is organized by the group “Mathematical Logic and Interdisciplinary Applications of Logic” of the University of Hamburg, Germany.

The conference will cover the whole range of mathematical logic and the foundations of the exact sciences, in particular, logic in philosophy, computer science and artificial intelligence.

Keynote Speakers.

In addition to the keynote talks, there will be a “PhD Colloquium” with invited presentations of excellent recent PhD graduates.

The programme committee invites the submission of abstracts for talks in all fields of research covered by the DVMLG: mathematical logic and the foundations of the exact sciences (including logic in philosophy, computer science and artificial intelligence).

Abstracts should have between 100 and 500 words and are to be submitted via the easychair submission page

The submission deadline is
