Theorem ablprop 20040
Description: If two structures have the same group components (properties), one is an Abelian group iff the other one is. (Contributed by NM, 11-Oct-2013.)
Hypotheses
Ref Expression
ablprop.b (Base‘𝐾) = (Base‘𝐿)
ablprop.p (+g‘𝐾) = (+g‘𝐿)
Assertion
Ref Expression
ablprop (𝐾 ∈ Abel ↔ 𝐿 ∈ Abel)

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