SMALL PERTURBATIONS OF C-STAR-DYNAMICAL SYSTEMS
It is shown that if δ is the generator of a strongly continuous oneparameter group of *-automorphisms of a C*-algebra A and δ′ is an unbounded *-derivation of A with the same domain as δ, then δ+αδ′ is also a generator for all sufficiently small real numbers α. © 1979 Springer-Verlag.
