Theorem mthmpps 36514

Description: Given a theorem, there is an explicitly definable witnessing provable pre-statement for the provability of the theorem. (However, this pre-statement requires infinitely many disjoint variable conditions, which is sometimes inconvenient.) (Contributed by Mario Carneiro, 18-Jul-2016.)

**Hypotheses**
Ref	Expression
mthmpps.r	⊢ 𝑅 = (mStRed‘𝑇)
mthmpps.j	⊢ 𝐽 = (mPPSt‘𝑇)
mthmpps.u	⊢ 𝑈 = (mThm‘𝑇)
mthmpps.d	⊢ 𝐷 = (mDV‘𝑇)
mthmpps.v	⊢ 𝑉 = (mVars‘𝑇)
mthmpps.z	⊢ 𝑍 = ∪ (𝑉 “ (𝐻 ∪ {𝐴}))
mthmpps.m	⊢ 𝑀 = (𝐶 ∪ (𝐷 ∖ (𝑍 × 𝑍)))

**Assertion**
Ref	Expression
mthmpps	⊢ (𝑇 ∈ mFS → (⟨𝐶, 𝐻, 𝐴⟩ ∈ 𝑈 ↔ (⟨𝑀, 𝐻, 𝐴⟩ ∈ 𝐽 ∧ (𝑅‘⟨𝑀, 𝐻, 𝐴⟩) = (𝑅‘⟨𝐶, 𝐻, 𝐴⟩))))

Proof of Theorem mthmpps Dummy variable 𝑥 is distinct from all other variables.
