A remark on the growth rate of operator semigroups under resolvent bounds

  • Filippo Dell’Oro

摘要

We provide a growth bound for the operator norm of \(C_0\) C 0 -semigroups on Hilbert spaces under a corresponding growth bound on the resolvent of the semigroup generator. For some super-linear resolvent growths, our estimate is sharper than the ones currently available in the literature.
