We generalize a result for the translation C0-semigroup on Lp(R+,μ)
about the equivalence of being chaotic and satisfying the Frequent
Hypercyclicity criterion due to Mangino and Peris to certain weighted
composition C0-semigroups. Such C0-semigroups appear in a natural way
when dealing with initial value problems for linear first order partial
differential operators. We apply our result to the linear von Foerster-Lasota
equation arising in mathematical biology. Weighted composition C0-semigroups
on Sobolev spaces are also considered.Comment: 12 page
