Theorem ostthlem1 27119

Description: Lemma for ostth 27131. If two absolute values agree on the positive integers greater than one, then they agree for all rational numbers and thus are equal as functions. (Contributed by Mario Carneiro, 9-Sep-2014.)

**Hypotheses**
Ref	Expression
qrng.q	⊢ 𝑄 = (ℂ_fld ↾_s ℚ)
qabsabv.a	⊢ 𝐴 = (AbsVal‘𝑄)
ostthlem1.1	⊢ (𝜑 → 𝐹 ∈ 𝐴)
ostthlem1.2	⊢ (𝜑 → 𝐺 ∈ 𝐴)
ostthlem1.3	⊢ ((𝜑 ∧ 𝑛 ∈ (ℤ_≥‘2)) → (𝐹‘𝑛) = (𝐺‘𝑛))

**Assertion**
Ref	Expression
ostthlem1	⊢ (𝜑 → 𝐹 = 𝐺)

Distinct variable groups: 𝑛,𝐺 𝜑,𝑛 𝐴,𝑛 𝑄,𝑛 𝑛,𝐹

Proof of Theorem ostthlem1 Dummy variables 𝑘 𝑦 are mutually distinct and distinct from all other variables.
