Circuit Bounds for Conjunctive Queries with Self-joins
Summary: Circuit size bounds for CQs under semiring semantics; extends Boolean self-join-free k-clique lower bounds. Relates self-join CQ complexity to self-join-free cases via semiring-specific correspondences and introduces endomorphism-based analysis. (summarized by gpt-5-nano on Feb 09 2026)
