Dynamic Networks of Concurret Pushdown Systems (DCPS)
From Progressive Runs for VASSB to Reachability
Conclusion, Acknowledgment & References
A. Strengthening Fairness to Progressive Runs
Lemma 6.1. A DCPS has a starving run if and only if it has a consistent run.
In this section, we prove Lemma 6.7. It will be convenient to use a slightly modified definition of pushdown automata for this.
