Sensitivity of non-autonomous discrete dynamical systems revisited

In this note, we construct a transitive nonautonomous discrete system with strongly periodic density which is not sensitive.Besides, we prove that every transitive nonautonomous discrete system with almost periodic density is syndetically sensitive,provided that it converges uniformly to a map, and that a product system is multisensitive (resp., \(\mathcal{F}\)sensitive) if and only if there exists a factor system is multisensitive (resp., \(\mathcal{F}\)sensitive),where \(\mathcal{F}\) is a filterdual.
