Theorem tendofset 41908

Description: The set of all trace-preserving endomorphisms on the set of translations for a lattice 𝐾. (Contributed by NM, 8-Jun-2013.)

Hypotheses

Ref	Expression
tendoset.l	⊢ ≤ = (le‘𝐾)
tendoset.h	⊢ 𝐻 = (LHyp‘𝐾)

Assertion

Ref	Expression
tendofset	⊢ (𝐾 ∈ 𝑉 → (TEndo‘𝐾) = (𝑤 ∈ 𝐻 ↦ {𝑠 ∣ (𝑠:((LTrn‘𝐾)‘𝑤)⟶((LTrn‘𝐾)‘𝑤) ∧ ∀𝑓 ∈ ((LTrn‘𝐾)‘𝑤)∀𝑔 ∈ ((LTrn‘𝐾)‘𝑤)(𝑠‘(𝑓 ∘ 𝑔)) = ((𝑠‘𝑓) ∘ (𝑠‘𝑔)) ∧ ∀𝑓 ∈ ((LTrn‘𝐾)‘𝑤)(((trL‘𝐾)‘𝑤)‘(𝑠‘𝑓)) ≤ (((trL‘𝐾)‘𝑤)‘𝑓))}))

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

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

Proof of Theorem tendofset

Dummy variable 𝑘 is distinct from all other variables.
