摘 要: | 1 IntroductionLet M be a manifold (possibly with boundary), and F : M → M be continuous. Call a closed invariant set A (?) M an adic attractor of f if it attracts almost all points (in the sense of Lebesgue measure) and the restriction f|A is topologically conjugate to an adic system. Such an attractor A is called n-adic if the restriction f|A can be topologically conjugate the n-adic system.
