Abstract
We generalized Boshernitzan's quantitative recurrence theorem to general group actions. Let (X, d) be a metric space with a finite measure and G be a countable group acting on (X, d). Assume that the action of G on (X, d) is measure preserving and let Fn ⊂ G be a sequence with |F n| ↑ ∞ and put . Then we have for almost every x, where α is the Hausdorff dimension of (X, d).
