Theorem 1arith 16895

Description: Fundamental theorem of arithmetic, where a prime factorization is represented as a sequence of prime exponents, for which only finitely many primes have nonzero exponent. The function 𝑀 maps the set of positive integers one-to-one onto the set of prime factorizations 𝑅. (Contributed by Paul Chapman, 17-Nov-2012.) (Proof shortened by Mario Carneiro, 30-May-2014.)

**Hypotheses**
Ref	Expression
1arith.1	⊢ 𝑀 = (𝑛 ∈ ℕ ↦ (𝑝 ∈ ℙ ↦ (𝑝 pCnt 𝑛)))
1arith.2	⊢ 𝑅 = {𝑒 ∈ (ℕ₀ ↑_m ℙ) ∣ (^◡𝑒 “ ℕ) ∈ Fin}

**Assertion**
Ref	Expression
1arith	⊢ 𝑀:ℕ–1-1-onto→𝑅

Distinct variable groups: 𝑒,𝑛,𝑝 𝑒,𝑀 𝑅,𝑛 Allowed substitution hints: 𝑅(𝑒,𝑝) 𝑀(𝑛,𝑝)

Proof of Theorem 1arith Dummy variables 𝑓 𝑔 𝑘 𝑞 𝑥 𝑦 are mutually distinct and distinct from all other variables.
