Workshop on Proof Theory, Modal Logic and Reflection Principles

The international workshop "Proof Theory, Modal Logic and Reflection Principles", also known as the “Wormshop”, will take place at Steklov Institute of Mathematics in Moscow, Russia, from 17.10.2017 to 20.10.2017.

In recent years an approach has been developed for the ordinal analysis of formal theories, based on the study of modal properties of reflection principles. This approach requires techniques from many disciplines; the aim of this workshop is to bring together experts in relevant fields in order to discuss recent advances and foster new collaborations.

Topics include but are not restricted to:

Provability logics and algebras
Turing-Feferman progressions
Weak fragments of modal logics
Proof theory and ordinal analysis
Fragments of first-order arithmetic
Modalities in topology and set theory
Axiomatic theories of truth

The workshop is the 4-th conference in the series. The previous conferences took place in Barcelona (2012), Mexico City (2014) and Tbilisi (2016).
