Theorem voliunnfl 32623
 Description: voliun 23129 is incompatible with the Feferman-Levy model; in that model, therefore, the Lebesgue measure as we've defined it isn't actually a measure. (Contributed by Brendan Leahy, 16-Dec-2017.)
Hypotheses

voliunnfl.1 𝑆 = seq1( + , 𝐺)
voliunnfl.2 𝐺 = (𝑛 ∈ ℕ ↦ (vol‘(𝑓𝑛)))
voliunnfl.3 ((∀𝑛 ∈ ℕ ((𝑓𝑛) ∈ dom vol ∧ (vol‘(𝑓𝑛)) ∈ ℝ) ∧ Disj 𝑛 ∈ ℕ (𝑓𝑛)) → (vol‘ 𝑛 ∈ ℕ (𝑓𝑛)) = sup(ran 𝑆, ℝ*, < ))
Assertion
Ref Expression
voliunnfl ((𝐴 ≼ ℕ ∧ ∀𝑥𝐴 𝑥 ≼ ℕ) → 𝐴 ≠ ℝ)
Distinct variable group:   𝑓,𝑛,𝑥,𝐴
Allowed substitution hints:   𝑆(𝑥,𝑓,𝑛)   𝐺(𝑥,𝑓,𝑛)

Proof of Theorem voliunnfl
Dummy variables 𝑔 𝑚 𝑙 are mutually distinct and distinct from all other variables.
