Every operator in the weakly closed operator algebra generated by a spectral
operator of scalar type and the projections in its resolution of the identity is a
spectral operator of scalar type . Proof . Since a spectral operator of scalar type is

Then , since the collection of finite sums of projections E ( n ; T ' ) is uniformly
bounded , it is clear from [ * ] that the collection of finite sums of projections E ( Mn
; T + P ) , n 2 K , is uniformly bounded . Moreover , Erap ( Elan ; T ) – Elun ; T + P ...
