Theorem adjval 29670

Description: Value of the adjoint function for 𝑇 in the domain of adj_ℎ. (Contributed by NM, 19-Feb-2006.) (Revised by Mario Carneiro, 24-Dec-2016.) (New usage is discouraged.)

Assertion

Ref	Expression
adjval	⊢ (𝑇 ∈ dom adjℎ → (adjℎ‘𝑇) = (℩𝑢 ∈ ( ℋ ↑m ℋ)∀𝑥 ∈ ℋ ∀𝑦 ∈ ℋ (𝑥 ·ih (𝑇‘𝑦)) = ((𝑢‘𝑥) ·ih 𝑦)))

Distinct variable group:   𝑥,𝑢,𝑦,𝑇

Proof of Theorem adjval

Dummy variable 𝑡 is distinct from all other variables.
