Theorem eigvalfval 29311

Description: The eigenvalues of eigenvectors of a Hilbert space operator. (Contributed by NM, 11-Mar-2006.) (New usage is discouraged.)

Assertion

Ref	Expression
eigvalfval	⊢ (𝑇: ℋ⟶ ℋ → (eigval‘𝑇) = (𝑥 ∈ (eigvec‘𝑇) ↦ (((𝑇‘𝑥) ·ih 𝑥) / ((normℎ‘𝑥)↑2))))

Distinct variable group:   𝑥,𝑇

Proof of Theorem eigvalfval

Dummy variable 𝑡 is distinct from all other variables.
