Query: Notes on solution maps of abstract FDEs   It is shown that the solution maps of an abstract functional differential
equations (FDEs) are $\alpha$-contractions in the phase space equipped with an
equivalent norm under appropriate assumptions. This result can be applied to
time-delayed reaction-diffusion equations and other evolution systems with time
delay.
