Theorem adjval 29971
Description: Value of the adjoint function for 𝑇 in the domain of adj. (Contributed by NM, 19-Feb-2006.) (Revised by Mario Carneiro, 24-Dec-2016.) (New usage is discouraged.)
Assertion
Ref Expression
adjval (𝑇 ∈ dom adj → (adj𝑇) = (𝑢 ∈ ( ℋ ↑m ℋ)∀𝑥 ∈ ℋ ∀𝑦 ∈ ℋ (𝑥 ·ih (𝑇𝑦)) = ((𝑢𝑥) ·ih 𝑦)))
Distinct variable group:   𝑥,𝑢,𝑦,𝑇

Proof of Theorem adjval
Dummy variable 𝑡 is distinct from all other variables.
