On the magnification of cantor sets and their limit models

  • Tim Bedford
  • Albert M. Fisher


For aC1+γ hyperbolic (cookie-cutter) Cantor setC we consider the limits of sequences of closed subsets ofR obtained by arbitrarily high magnifications around different points ofC. It is shown that a well defined set of limit models exists for the infinitesimal geometry, orscenery, in the Cantor set. IfCC} is a diffeomorphic copy ofC then the set of limit models of C is the same as that ofC. Furthermore every limit model is made of Cantor sets which areC1+γ diffeomorphic withC (for some γ>0, γ∈(0,1)), but not all suchC1+γ copies ofC occur in the limit models. We show the relation between this approach to the asymptotic structure of a Cantor set and Sullivan's “scaling function”. An alternative definition of a fractal is discussed.
