摘要
We give necessary and sufficient conditions for an operator A on a Hilbert space to have a bounded H∞-calculus on a vertical strip symmetric to the imaginary axis. From this, a characterization of group generators on Hilbert spaces is obtained yielding recent results of Liu and Zwart as corollaries.
