Theorem vmcn 30628

Description: Vector subtraction is jointly continuous in both arguments. (Contributed by Mario Carneiro, 6-May-2014.) (New usage is discouraged.)

**Hypotheses**
Ref	Expression
vmcn.c	⊢ 𝐶 = (IndMet‘𝑈)
vmcn.j	⊢ 𝐽 = (MetOpen‘𝐶)
vmcn.m	⊢ 𝑀 = ( −_𝑣 ‘𝑈)

**Assertion**
Ref	Expression
vmcn	⊢ (𝑈 ∈ NrmCVec → 𝑀 ∈ ((𝐽 ×_t 𝐽) Cn 𝐽))

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