摘要
We characterize the polynomial decay of orbits of Hilbert space C-0-semigroups in resolvent terms. We also show that results of the same type for general Banach space semigroups and functions obtained recently in Batty and Duyckaerts (J Evol Eq 8: 765-780, 2008) are sharp. This settles a conjecture posed in Batty and Duyckaerts (2008).
