Consistent Query Answering for Primary Keys on Rooted Tree Queries
Summary: CQA with primary-key violations for rooted-tree Boolean CQs; CERTAINTY(q) falls into three regimes: FO, NL-hard with LFP, or coNP-complete, determinable in polynomial time from q. CFG-based fixpoint algorithm with homomorphism criteria; extends to broader PK schemas with simple keys.
