In this talk, I will present recent results on linear retarded functional equations, dealing first with on difference equations and then with the measure-valued case. The focus will be on (exponential) stability characterizations, especially by investigating general instances of the Hale-Silkowski criterium.

This is joint work F. Netto and G. Mazanti
