Theorem dvaset 42156

Description: The constructed partial vector space A for a lattice 𝐾. (Contributed by NM, 8-Oct-2013.) (Revised by Mario Carneiro, 22-Jun-2014.)

Hypotheses

Ref	Expression
dvaset.h	⊢ 𝐻 = (LHyp‘𝐾)
dvaset.t	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)
dvaset.e	⊢ 𝐸 = ((TEndo‘𝐾)‘𝑊)
dvaset.d	⊢ 𝐷 = ((EDRing‘𝐾)‘𝑊)
dvaset.u	⊢ 𝑈 = ((DVecA‘𝐾)‘𝑊)

Assertion

Ref	Expression
dvaset	⊢ ((𝐾 ∈ 𝑋 ∧ 𝑊 ∈ 𝐻) → 𝑈 = ({⟨(Base‘ndx), 𝑇⟩, ⟨(+g‘ndx), (𝑓 ∈ 𝑇, 𝑔 ∈ 𝑇 ↦ (𝑓 ∘ 𝑔))⟩, ⟨(Scalar‘ndx), 𝐷⟩} ∪ {⟨( ·𝑠 ‘ndx), (𝑠 ∈ 𝐸, 𝑓 ∈ 𝑇 ↦ (𝑠‘𝑓))⟩}))

Distinct variable groups:   𝑓,𝑔,𝑠,𝐾   𝑓,𝑊,𝑔,𝑠

Allowed substitution hints:   𝐷(𝑓, 𝑔, 𝑠)   𝑇(𝑓, 𝑔, 𝑠)   𝑈(𝑓, 𝑔, 𝑠)   𝐸(𝑓, 𝑔, 𝑠)   𝐻(𝑓, 𝑔, 𝑠)   𝑋(𝑓, 𝑔, 𝑠)

Proof of Theorem dvaset

Dummy variable 𝑤 is distinct from all other variables.
