Definition df-st

Description: Define the set of states on a Hilbert lattice. Definition of Kalmbach p. 266. (Contributed by NM, 23-Oct-1999) (New usage is discouraged.)

Ref Expression
Assertion df-st States = { 𝑓 ∈ ( ( 0 [,] 1 ) ↑m Cℋ ) ∣ ( ( 𝑓 ‘ ℋ ) = 1 ∧ ∀ 𝑥 ∈ Cℋ ∀ 𝑦 ∈ Cℋ ( 𝑥 ⊆ ( ⊥ ‘ 𝑦 ) → ( 𝑓 ‘ ( 𝑥 ∨ℋ 𝑦 ) ) = ( ( 𝑓 ‘ 𝑥 ) + ( 𝑓 ‘ 𝑦 ) ) ) ) }
