To circumvent these pathologies, we introduce strength-ened forms of compactness, discreteness, and Hausdorﬀness which are better behaved in subsystems of second-order arithmetic weaker than ACA0.

There are many named subsystems of second-order arithmetic. A subscript 0 in the name of a subsystem indicates that it includes only a restricted portion of the full second-order induction scheme (Friedman 1976). Such a restriction lowers the proof-theoretic strength of the system significantly.
