On the Expressive Power of Datalog: Tools and a Case Study

Summary: Characterizes Datalog(!=) as a fragment of infinitary logic L^infty via pebble games, giving tools for expressiveness analysis. Applies them to classify fixed directed subgraph homeomorphism queries and proves Fortune et al.'s dichotomies proper for Datalog(!=) expressibility without complexity assumptions.
