Theorem lnof 30578

Description: A linear operator is a mapping. (Contributed by NM, 4-Dec-2007.) (Revised by Mario Carneiro, 18-Nov-2013.) (New usage is discouraged.)

**Hypotheses**
Ref	Expression
lnof.1	⊢ 𝑋 = (BaseSet‘𝑈)
lnof.2	⊢ 𝑌 = (BaseSet‘𝑊)
lnof.7	⊢ 𝐿 = (𝑈 LnOp 𝑊)

**Assertion**
Ref	Expression
lnof	⊢ ((𝑈 ∈ NrmCVec ∧ 𝑊 ∈ NrmCVec ∧ 𝑇 ∈ 𝐿) → 𝑇:𝑋⟶𝑌)

Proof of Theorem lnof Dummy variables 𝑥 𝑦 𝑧 are mutually distinct and distinct from all other variables.
