Defining Relations on Graphs: How Hard is it in the Presence of Node Partitions?
Summary: Analyze the definability problem on node-labeled graphs (node-partitions induced by value-equality) for extensions of regular path queries: REM and REE. Show REM definability EXPSPACE-complete, REE PSPACE-complete, and UCQ(REM/REE) coNP-complete. (summarized by gpt-5-mini on Feb 09 2026)
