The fact that a finite number of commuting spectral operators in a Hilbert space can be simultaneously transformed into normal operators by passing to an equivalent inner product is due to Wermer [ 3 ] . He based his argument on a ...

Introduction > The sum and product of two commuting bounded normal operators in Hilbert space is normal and hence spectral . In Corollary XV.6.5 it was seen that this principle could be extended to the sum and product of two commuting ...
