Publications - BPA bisimilarity is EXPTIME-hard


Stefan Kiefer. BPA bisimilarity is EXPTIME-hard. Information Processing Letters (IPL), 113(4):101–106, 2013.


Given a basic process algebra (BPA) and two stack symbols, the BPA bisimilarity problem asks whether the two stack symbols are bisimilar. We show that this problem is EXPTIME-hard.
