Theorem aspval2 21102

Description: The algebraic closure is the ring closure when the generating set is expanded to include all scalars. EDITORIAL : In light of this, is AlgSpan independently needed? (Contributed by Stefan O'Rear, 9-Mar-2015.)

Hypotheses

Ref	Expression
aspval2.a	⊢ 𝐴 = (AlgSpan‘𝑊)
aspval2.c	⊢ 𝐶 = (algSc‘𝑊)
aspval2.r	⊢ 𝑅 = (mrCls‘(SubRing‘𝑊))
aspval2.v	⊢ 𝑉 = (Base‘𝑊)

Assertion

Ref	Expression
aspval2	⊢ ((𝑊 ∈ AssAlg ∧ 𝑆 ⊆ 𝑉) → (𝐴‘𝑆) = (𝑅‘(ran 𝐶 ∪ 𝑆)))

Proof of Theorem aspval2

Dummy variable 𝑥 is distinct from all other variables.
