Theorem mfsdisj 35555
Description: The constants and variables of a formal system are disjoint. (Contributed by Mario Carneiro, 18-Jul-2016.)
Hypotheses
Ref Expression
mfsdisj.c 𝐶 = (mCN‘𝑇)
mfsdisj.v 𝑉 = (mVR‘𝑇)
Assertion
Ref Expression
mfsdisj (𝑇 ∈ mFS → (𝐶𝑉) = ∅)

Proof of Theorem mfsdisj
Dummy variable 𝑣 is distinct from all other variables.
