Description: The division rings on trace-preserving endomorphisms for a lattice 𝐾. (Contributed by NM, 8-Jun-2013.)
Hypothesis
Ref Expression
erngset.h 𝐻 = (LHyp‘𝐾)
Assertion
Ref Expression
erngfset (𝐾𝑉 → (EDRing‘𝐾) = (𝑤𝐻 ↦ {⟨(Base‘ndx), ((TEndo‘𝐾)‘𝑤)⟩, ⟨(+g‘ndx), (𝑠 ∈ ((TEndo‘𝐾)‘𝑤), 𝑡 ∈ ((TEndo‘𝐾)‘𝑤) ↦ (𝑓 ∈ ((LTrn‘𝐾)‘𝑤) ↦ ((𝑠𝑓) ∘ (𝑡𝑓))))⟩, ⟨(.r‘ndx), (𝑠 ∈ ((TEndo‘𝐾)‘𝑤), 𝑡 ∈ ((TEndo‘𝐾)‘𝑤) ↦ (𝑠𝑡))⟩}))
Distinct variable groups:   𝑤,𝐻   𝑓,𝑠,𝑡,𝑤,𝐾
Allowed substitution hints:   𝐻(𝑡,𝑓,𝑠)   𝑉(𝑤,𝑡,𝑓,𝑠)

Proof of Theorem erngfset
Dummy variable 𝑘 is distinct from all other variables.
