RCA 0 is the system with Δ 1 0 comprehension and Σ 1 0 induction on the natural numbers. WKL 0 is RCA 0 plus weak König's lemma for trees of finite sequences of 0's and 1's. Within RCA 0 we encode a separable Banach space Â as a countable normed space A over Q.Points of …

http://www.personal.psu.edu/t20/papers/article-l/node2.html 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. For example, the system ACA0 described below is equiconsistent with Peano arithmetic. The corresponding theory ACA, consisting of ACA0 plus th…

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.
