Theorem lcdlvec 37661

Description: The dual vector space of functionals with closed kernels is a left vector space. (Contributed by NM, 14-Mar-2015.)

**Hypotheses**
Ref	Expression
lcdlmod.h	⊢ 𝐻 = (LHyp‘𝐾)
lcdlmod.c	⊢ 𝐶 = ((LCDual‘𝐾)‘𝑊)
lcdlmod.k	⊢ (𝜑 → (𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻))

**Assertion**
Ref	Expression
lcdlvec	⊢ (𝜑 → 𝐶 ∈ LVec)

Proof of Theorem lcdlvec Dummy variable 𝑓 is distinct from all other variables.
