Then T is a spectral operator if and only if ( a ) the family of projections E ( 0 ; T ' ) corresponding to compact spectral sets of T is uniformly bounded , and ( b ) no non - zero x in X satisfies the equation E ( o ) x = 0 for every ...

Moreover , if C belongs to the trace class C1 , then T , C converges to zero in trace norm , and CT * converges to zero in trace norm . PROOF . The set K = C ( { x H || æ $ 1 } ) is conditionally compact , and thus for each ε > 0 there ...
