Description: First substitution for the adjunct (cofactor) matrix. (Contributed by SO, 11-Jul-2018.)

Hypotheses

Ref	Expression
madufval.a	⊢ 𝐴 = (𝑁 Mat 𝑅)
madufval.d	⊢ 𝐷 = (𝑁 maDet 𝑅)
madufval.j	⊢ 𝐽 = (𝑁 maAdju 𝑅)
madufval.b	⊢ 𝐵 = (Base‘𝐴)
madufval.o	⊢ 1 = (1r‘𝑅)
madufval.z	⊢ 0 = (0g‘𝑅)

Assertion

Ref	Expression
madufval	⊢ 𝐽 = (𝑚 ∈ 𝐵 ↦ (𝑖 ∈ 𝑁, 𝑗 ∈ 𝑁 ↦ (𝐷‘(𝑘 ∈ 𝑁, 𝑙 ∈ 𝑁 ↦ if(𝑘 = 𝑗, if(𝑙 = 𝑖, 1 , 0 ), (𝑘𝑚𝑙))))))

Distinct variable groups:   𝑚,𝑁,𝑖,𝑗,𝑘,𝑙   𝑅,𝑚,𝑖,𝑗,𝑘,𝑙   𝐵,𝑚

Allowed substitution hints:   𝐴(𝑖, 𝑗, 𝑘, 𝑚, 𝑙)   𝐵(𝑖, 𝑗, 𝑘, 𝑙)   𝐷(𝑖, 𝑗, 𝑘, 𝑚, 𝑙)   1 (𝑖, 𝑗, 𝑘, 𝑚, 𝑙)   𝐽(𝑖, 𝑗, 𝑘, 𝑚, 𝑙)   0 (𝑖, 𝑗, 𝑘, 𝑚, 𝑙)

Proof of Theorem madufval

Dummy variables 𝑛 𝑟 are mutually distinct and distinct from all other variables.
