The Complexity of Data Exchange
Summary: Shows weak acyclicity and a fixed mapping indispensable: slightest relaxation of weak acyclicity yields undecidability (via universal-algebra), and allowing the mapping as input makes the existence-of-solutions problem EXPTIME-complete. Classifies combined complexity for natural mapping restrictions as EXPTIME- or coNP-complete. (summarized by gpt-5-mini on Feb 09 2026)
