Theorem elmrsubrn 35495

Description: Characterization of the substitutions as functions from expressions to expressions that distribute under concatenation and map constants to themselves. (The constant part uses (𝐶 ∖ 𝑉) because we don't know that 𝐶 and 𝑉 are disjoint until we get to ismfs 35524.) (Contributed by Mario Carneiro, 18-Jul-2016.)

**Hypotheses**
Ref	Expression
mrsubccat.s	⊢ 𝑆 = (mRSubst‘𝑇)
mrsubccat.r	⊢ 𝑅 = (mREx‘𝑇)
mrsubcn.v	⊢ 𝑉 = (mVR‘𝑇)
mrsubcn.c	⊢ 𝐶 = (mCN‘𝑇)

**Assertion**
Ref	Expression
elmrsubrn	⊢ (𝑇 ∈ 𝑊 → (𝐹 ∈ ran 𝑆 ↔ (𝐹:𝑅⟶𝑅 ∧ ∀𝑐 ∈ (𝐶 ∖ 𝑉)(𝐹‘⟨“𝑐”⟩) = ⟨“𝑐”⟩ ∧ ∀𝑥 ∈ 𝑅 ∀𝑦 ∈ 𝑅 (𝐹‘(𝑥 ++ 𝑦)) = ((𝐹‘𝑥) ++ (𝐹‘𝑦)))))

Distinct variable groups: 𝑥,𝑐,𝑦,𝐶 𝑥,𝑅,𝑦 𝑆,𝑐,𝑥,𝑦 𝑥,𝑇,𝑦 𝐹,𝑐,𝑥,𝑦 𝑉,𝑐,𝑥,𝑦 𝑥,𝑊,𝑦 Allowed substitution hints: 𝑅(𝑐) 𝑇(𝑐) 𝑊(𝑐)

Proof of Theorem elmrsubrn Dummy variables 𝑟 𝑣 𝑤 are mutually distinct and distinct from all other variables.
