Abstract
The family of operators, where V is an injective S-Volterra operator (that is, [S, V] = V2) and –A ≡ –V−1 generates a uniformly bounded C0-semigroup, is studied in the context of similarity and of the weaker quasi-affinity relation. It is shown that S is similar to for all 1, and is a quasi-affine transform of S + tVα for all t ≥ 0 and 0 < α < 1.
