Theorem pmaplubN 39885
Description: The LUB of a projective map is the projective map's argument. (Contributed by NM, 13-Mar-2012.) (New usage is discouraged.)
Hypotheses
Ref Expression
pmaplub.b 𝐵 = (Base‘𝐾)
pmaplub.u 𝑈 = (lub‘𝐾)
pmaplub.m 𝑀 = (pmap‘𝐾)
Assertion
Ref Expression
pmaplubN ((𝐾 ∈ HL ∧ 𝑋𝐵) → (𝑈‘(𝑀𝑋)) = 𝑋)

Proof of Theorem pmaplubN
Dummy variable 𝑝 is distinct from all other variables.
