Web1 Jan 1985 · We work in the context of weak subsystems of second order arithmetic. 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  as a countable normed space A over Q.Points of …
