Abstract: We show that a bounded homomorphism $T: L^1_{\omega}(\mathbb{R}^+)\to {\mathcal A}$ is equivalent to a uniformly bounded family of fractional homomorphisms $T_{\alpha}: AC^{(\alpha)}_{\omega}(\mathbb{R}^+)\to {\mathcal A}$ for any $\alpha>0$. We add this characterization to the Widder-Arendt-Kisynski theorem and relate it to $\alpha$-times integrated semigroups.
