The 4th I nternational Autumn School on Proof Theory in Utre cht is arranged under the auspices of The Proof So ciety and organised by the universities of Amsterd am and Utrecht. The Proof Society has recently bee n formed to support the notion of proof in its bro adest sense, through a series of suitable activiti es; to be therefore inclusive in reaching out to a ll scientific areas which consider proof as an obj ect in their studies; to enable the community to s hape its future by identifying, formulating and co mmunicating its most important goals; to actively promote proof to increase its visibility and repre sentation.

e five courses:

\n - **Computational Con
tent of Proofs** by Ulrich Berger (Swansea
University)

\n - **Proof-theoretic Seman
tics** by Bogdan Dicher (University of Lisb

\n - **Labelled Sequent Calculi by Marianna Girlando (University of Amsterdam
)\n - Proof Complexity by Ra
heleh Jalali (Utrecht University)\n - Proof Theory of Set Theory by Michael Ra
