Determinacy of Real Conjunctive Queries. The Boolean Case
Summary: Examines determinacy under bag (multiset) semantics: proves Boolean conjunctive-query determinacy decidable, but undecidable for unions of Boolean CQs—contrasting with set semantics where unions stay decidable. Shows path-query determinacy under bags equals set semantics (thus decidable). (summarized by gpt-5-mini on Feb 09 2026)
