Registration is open for the workshop "Proof Theory and Modal Logic". 
Researchers and students interested in proof theory, modal logic, ordinal analysis or other related
topics are encouraged to attend. 
It may also be possible to accommodate a few additional presentations.

To register, please contact Joost J. Joosten .

There is a registration fee of 80EUR. Upon registration you will receive information on the method 
of payment. Students and young researchers that wish to waive the fee should mention this when

Aims and scope

A Pi^0_1 ordinal analysis of Peano arithmetic can be based on provability logics with infinitely 
many modalities. The aims of the workshop are to report and to discuss progress on extending the 
analysis to stronger theories, as well as to study the corresponding logics and algebras from 
topological, set-theoretical and algebraic points of view.

Topics include but are not restricted to: reflection principles; Turing--Feferman recursive 
progressions; provability logics and algebras; conservation results for fragments of arithmetic 
and analysis; ordinal notation systems; topological and set-theoretic interpretations of modal logic.
