The paper "Folding systems of communicating agents"
in this volume, by myself and S.Paul, has a serious bug.
Philippe Darondeau gave us an example event structure from his paper
"Context-free event domains are recognizable" with
Eric Badouel and J.-C. Raoult (1999) on which our proof does not work.
