Theorem archrecpr 7436
Description: Archimedean principle for positive reals (reciprocal version). (Contributed by Jim Kingdon, 25-Nov-2020.)
Assertion
Ref Expression
archrecpr (𝐴P → ∃𝑗N ⟨{𝑙𝑙 <Q (*Q‘[⟨𝑗, 1o⟩] ~Q )}, {𝑢 ∣ (*Q‘[⟨𝑗, 1o⟩] ~Q ) <Q 𝑢}⟩<P 𝐴)
Distinct variable groups:   𝐴,𝑗   𝑗,𝑙,𝑢
Allowed substitution hints:   𝐴(𝑢,𝑙)

Proof of Theorem archrecpr
Dummy variable 𝑥 is distinct from all other variables.
