Theorem dibf11N 38299

Description: The partial isomorphism A for a lattice 𝐾 is a one-to-one function. Part of Lemma M of [Crawley] p. 120 line 27. (Contributed by NM, 4-Dec-2013.) (New usage is discouraged.)

Hypotheses

Ref	Expression
dibcl.h	⊢ 𝐻 = (LHyp‘𝐾)
dibcl.i	⊢ 𝐼 = ((DIsoB‘𝐾)‘𝑊)

Assertion

Ref	Expression
dibf11N	⊢ ((𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻) → 𝐼:dom 𝐼–1-1-onto→ran 𝐼)

Proof of Theorem dibf11N

Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
