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

Ref Expression
Hypotheses erngset.h ⊢ 𝐻 = ( LHyp ‘ 𝐾 )
erngset.t ⊢ 𝑇 = ( ( LTrn ‘ 𝐾 ) ‘ 𝑊 )
erngset.e ⊢ 𝐸 = ( ( TEndo ‘ 𝐾 ) ‘ 𝑊 )
erngset.d ⊢ 𝐷 = ( ( EDRing ‘ 𝐾 ) ‘ 𝑊 )
Assertion erngset ( ( 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 ↦ ( 𝑠 ∘ 𝑡 ) ) ⟩ } )
