Theorem padicabvf 27584

Description: The p-adic absolute value is an absolute value. (Contributed by Mario Carneiro, 9-Sep-2014.)

**Hypotheses**
Ref	Expression
qrng.q	⊢ 𝑄 = (ℂ_fld ↾_s ℚ)
qabsabv.a	⊢ 𝐴 = (AbsVal‘𝑄)
padic.j	⊢ 𝐽 = (𝑞 ∈ ℙ ↦ (𝑥 ∈ ℚ ↦ if(𝑥 = 0, 0, (𝑞↑-(𝑞 pCnt 𝑥)))))

**Assertion**
Ref	Expression
padicabvf	⊢ 𝐽:ℙ⟶𝐴

Distinct variable groups: 𝑥,𝑞,𝐴 𝑥,𝑄 Allowed substitution hints: 𝑄(𝑞) 𝐽(𝑥,𝑞)

Proof of Theorem padicabvf Dummy variable 𝑝 is distinct from all other variables.
