Theorem pmap0 39766

Description: Value of the projective map of a Hilbert lattice at lattice zero. Part of Theorem 15.5.1 of [MaedaMaeda] p. 62. (Contributed by NM, 17-Oct-2011.)

Hypotheses

Ref	Expression
pmap0.z	⊢ 0 = (0.‘𝐾)
pmap0.m	⊢ 𝑀 = (pmap‘𝐾)

Assertion

Ref	Expression
pmap0	⊢ (𝐾 ∈ AtLat → (𝑀‘ 0 ) = ∅)

Proof of Theorem pmap0

Dummy variable 𝑎 is distinct from all other variables.
