The Complexity of Boolean Conjunctive Queries with Intersection Joins

Summary: Reduce BCQs with intersection joins to disjunctions of equality-join BCQs, yielding ij-width that exactly captures their complexity. Define iota-acyclicity (alpha-acyclicity analogue) characterising near-linear evaluation; non-iota queries are triangle-hard. (summarized by gpt-5-mini on Feb 09 2026)
