Query: On a criterion for log-convex decay in non-selfadjoint dynamics   The short-time and global behaviour are studied for autonomous linear
evolution equations defined by generators of uniformly bounded holomorphic
semigroups in a Hilbert space. A general criterion for log-convexity in time of
the norm of the solution is treated. Strict decrease and differentiability at
the initial time results, with a derivative controlled by the lower bound of
the negative generator, which is proved strictly accretive with equal numerical
and spectral abscissas.
