Theorem mendval 39768
Description: Value of the module endomorphism algebra. (Contributed by Stefan O'Rear, 2-Sep-2015.)
Hypotheses
Ref Expression
mendval.b 𝐵 = (𝑀 LMHom 𝑀)
mendval.p + = (𝑥𝐵, 𝑦𝐵 ↦ (𝑥f (+g𝑀)𝑦))
mendval.t × = (𝑥𝐵, 𝑦𝐵 ↦ (𝑥𝑦))
mendval.s 𝑆 = (Scalar‘𝑀)
mendval.v · = (𝑥 ∈ (Base‘𝑆), 𝑦𝐵 ↦ (((Base‘𝑀) × {𝑥}) ∘f ( ·𝑠𝑀)𝑦))
Assertion
Ref Expression
mendval (𝑀𝑋 → (MEndo‘𝑀) = ({⟨(Base‘ndx), 𝐵⟩, ⟨(+g‘ndx), + ⟩, ⟨(.r‘ndx), × ⟩} ∪ {⟨(Scalar‘ndx), 𝑆⟩, ⟨( ·𝑠 ‘ndx), · ⟩}))
Distinct variable groups:   𝑥,𝑦,𝐵   𝑥,𝑀,𝑦
Allowed substitution hints:   + (𝑥,𝑦)   𝑆(𝑥,𝑦)   · (𝑥,𝑦)   × (𝑥,𝑦)   𝑋(𝑥,𝑦)

Proof of Theorem mendval
Dummy variables 𝑚 𝑏 are mutually distinct and distinct from all other variables.
