Theorem hommval 31755
Description: Value of the scalar product with a Hilbert space operator. (Contributed by NM, 20-Feb-2006.) (Revised by Mario Carneiro, 23-Aug-2014.) (New usage is discouraged.)
Assertion
Ref Expression
hommval ((𝐴 ∈ ℂ ∧ 𝑇: ℋ⟶ ℋ) → (𝐴 ·op 𝑇) = (𝑥 ∈ ℋ ↦ (𝐴 · (𝑇𝑥))))
Distinct variable groups:   𝑥,𝐴   𝑥,𝑇

Proof of Theorem hommval
Dummy variables 𝑓 𝑔 are mutually distinct and distinct from all other variables.
