Add to ORKGLet T be a semigroup of linear contractions on a Banach space X, and let Xs(T) = {x ∈ X : lims→∞ ∥T(s)x∥ = 0}. Then Xs(T) is the annihilator of the bounded trajectories of T*. If the unitary spectrum of T is countable, then Xs(T) is the annihilator of the unitary eigenvectors of T*, and lims ∥T(s)x∥ = inf{∥x - y∥ : y ∈ XS(T)} for each x in X
