Query: Minimal periods of semilinear evolution equations with Lipschitz
  nonlinearity revisited   We obtain a lower bound for the period of periodic solutions of semilinear
evolution equations for the full range of nonlinear terms for which standard
local existence theory applies. This lower bound depends on the Lipschitz
constant of the nonlinear term as an operator acting on the domain of a
fractional power of the linear operator into the base space.
