摘要
Given a dynamical system, we prove that the shortest distance between two n-orbits scales like n to a power even when the system has slow mixing properties, thus building and improving on results of Barros, Liao and the first author [On the shortest distance between orbits and the longest common substring problem. Adv. Math. 344 (2019), 311-339]. We also extend these results to flows. Finally, we give an example for which the shortest distance between two orbits has no scaling limit.
