Proof spectral theorem

Webon ℳ for Theorem (1.3) the General Transference Theorem likewise contains the spectral theorem for unitary operators [215]. Thus our results stemming from Theorems (1.31) and (1.21) (specifically, Theorems (1.32), (1.35), (1.36), and (1.39)) can be viewed as generalizing the spectral theorem from Hilbert space to arbitrary reflexive . ã ... WebProof of b). Suppose we have two distinct eigenvalues λ 6= µ. Then Ax = λx, Ay = µy, (3) where x,y are eigenvectors. Multiply the first equation on y, use (1) and the ... Then, by the Spectral Theorem for unitary matrices (section 3), there is another unitary matrix B such that
