Theorem dvhvbase 41746

Description: The vectors (vector base set) of the constructed full vector space H are all translations (for a fiducial co-atom 𝑊). (Contributed by NM, 2-Nov-2013.) (Revised by Mario Carneiro, 22-Jun-2014.)

Hypotheses

Ref	Expression
dvhvbase.h	⊢ 𝐻 = (LHyp‘𝐾)
dvhvbase.t	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)
dvhvbase.e	⊢ 𝐸 = ((TEndo‘𝐾)‘𝑊)
dvhvbase.u	⊢ 𝑈 = ((DVecH‘𝐾)‘𝑊)
dvhvbase.v	⊢ 𝑉 = (Base‘𝑈)

Assertion

Ref	Expression
dvhvbase	⊢ ((𝐾 ∈ 𝑋 ∧ 𝑊 ∈ 𝐻) → 𝑉 = (𝑇 × 𝐸))

Proof of Theorem dvhvbase

Dummy variables 𝑓 𝑔 ℎ 𝑠 are mutually distinct and distinct from all other variables.
