The Weisfeiler-Leman Dimension of Conjunctive Queries
Summary: Characterizes the WL-dimension of the answer-count function for any conjunctive query φ as sew(φ), a new semantic extension width combining the Gaifman treewidth and quantified-star-size. Extends full-CQ results and implies GNNs (via WL) need order ≥ sew(φ) to compute counts. (summarized by gpt-5-mini on Feb 09 2026)
