Theorem dvafset 42029

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

Hypothesis

Ref	Expression
dvaset.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
dvafset	⊢ (𝐾 ∈ 𝑉 → (DVecA‘𝐾) = (𝑤 ∈ 𝐻 ↦ ({⟨(Base‘ndx), ((LTrn‘𝐾)‘𝑤)⟩, ⟨(+g‘ndx), (𝑓 ∈ ((LTrn‘𝐾)‘𝑤), 𝑔 ∈ ((LTrn‘𝐾)‘𝑤) ↦ (𝑓 ∘ 𝑔))⟩, ⟨(Scalar‘ndx), ((EDRing‘𝐾)‘𝑤)⟩} ∪ {⟨( ·𝑠 ‘ndx), (𝑠 ∈ ((TEndo‘𝐾)‘𝑤), 𝑓 ∈ ((LTrn‘𝐾)‘𝑤) ↦ (𝑠‘𝑓))⟩})))

Distinct variable groups:   𝑤,𝐻   𝑓,𝑔,𝑠,𝑤,𝐾

Allowed substitution hints:   𝐻(𝑓, 𝑔, 𝑠)   𝑉(𝑤, 𝑓, 𝑔, 𝑠)

Proof of Theorem dvafset

Dummy variable 𝑘 is distinct from all other variables.
