Theorem zarclsiin 34382

Description: In a Zariski topology, the intersection of the closures of a family of ideals is the closure of the span of their union. (Contributed by Thierry Arnoux, 16-Jun-2024.)

**Hypotheses**
Ref	Expression
zarclsx.1	⊢ 𝑉 = (𝑖 ∈ (LIdeal‘𝑅) ↦ {𝑗 ∈ (PrmIdeal‘𝑅) ∣ 𝑖 ⊆ 𝑗})
zarclsiin.1	⊢ 𝐾 = (RSpan‘𝑅)

**Assertion**
Ref	Expression
zarclsiin	⊢ ((𝑅 ∈ Ring ∧ 𝑇 ⊆ (LIdeal‘𝑅) ∧ 𝑇 ≠ ∅) → ∩ 𝑙 ∈ 𝑇 (𝑉‘𝑙) = (𝑉‘(𝐾‘∪ 𝑇)))

Distinct variable groups: 𝑅,𝑖,𝑗,𝑙 𝑉,𝑙 𝑖,𝐾,𝑗,𝑙 𝑇,𝑖,𝑗,𝑙 Allowed substitution hints: 𝑉(𝑖, 𝑗)

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