We study the dynamical Borel–Cantelli lemma for recurrence sets in
a measure-preserving dynamical system (X, μ, T ) with a compatible metric d. We
prove that under some regularity conditions, the μ-measure
of the following set R(ψ) = {x ∈ X : d(T nx, x) < ψ(n) for infinitely many n ∈ N} obeys a zero–full law according to the convergence or divergence
of a certain series, where ψ : N → R+. The applications of our main theorem
include the Gauss map, β-transformation
and homogeneous self-similar sets.
