Description: The division ring on trace-preserving endomorphisms for a fiducial co-atom 𝑊. (Contributed by NM, 5-Jun-2013.) (New usage is discouraged.)

Hypotheses

Ref	Expression
erngset.h-r	⊢ 𝐻 = (LHyp‘𝐾)
erngset.t-r	⊢ 𝑇 = ((LTrn‘𝐾)‘𝑊)
erngset.e-r	⊢ 𝐸 = ((TEndo‘𝐾)‘𝑊)
erngset.d-r	⊢ 𝐷 = ((EDRingR‘𝐾)‘𝑊)

Assertion

Ref	Expression
erngset-rN	⊢ ((𝐾 ∈ 𝑉 ∧ 𝑊 ∈ 𝐻) → 𝐷 = {⟨(Base‘ndx), 𝐸⟩, ⟨(+g‘ndx), (𝑠 ∈ 𝐸, 𝑡 ∈ 𝐸 ↦ (𝑓 ∈ 𝑇 ↦ ((𝑠‘𝑓) ∘ (𝑡‘𝑓))))⟩, ⟨(.r‘ndx), (𝑠 ∈ 𝐸, 𝑡 ∈ 𝐸 ↦ (𝑡 ∘ 𝑠))⟩})

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

Allowed substitution hints:   𝐷(𝑡, 𝑓, 𝑠)   𝑇(𝑡, 𝑓, 𝑠)   𝐸(𝑡, 𝑓, 𝑠)   𝐻(𝑡, 𝑓, 𝑠)   𝑉(𝑡, 𝑓, 𝑠)

Proof of Theorem erngset-rN

Dummy variable 𝑤 is distinct from all other variables.
