WebOct 6, 2024 · We are asked to conclude (e) above, the spectral mapping theorem, which says $\sigma(\phi(f)) = \{ f(\lambda) \mid \lambda \in \sigma(A) \}$. I think I understand the continuous functional calculus, but I honestly have no idea about proving the spectral theorem using the given steps. All three of 1,2,3 elude me and I have no idea where to start. WebJan 3, 2010 · Narinder S Claire We give a direct non-abstract proof of the Spectral Mapping Theorem for the Helffer-Sjöstrand functional calculus for linear operators on Banach spaces with real spectra and consequently give a new non-abstract direct proof for the Spectral Mapping Theorem for self-adjoint operators on Hilbert spaces.

WebOct 17, 2024 · Basically, I want to show that σ ( α I) = { α } for any complex number α? I have shown that { α } ⊂ σ ( α I). How to show the other way round? Your last line refers to degree one polynomials, not constant polynomials. And the proof is elementary. I guess you mean σ ( a I) = a σ ( I). α I − λ I is not invertible iff λ = α.
