Conjunctive Regular Path Queries under Injective Semantics
Summary: Introduces atom- and query-injective semantics for CRPQs (injective-homomorphism generalizations of RPQ simple-path semantics) and studies evaluation and containment. Key findings: containment undecidable for atom-injective, PSPACE-complete for query-injective (vs EXPSPACE under standard semantics) and complete complexity maps for CQs and finite-language CRPQ fragments.
