Modified Miller dendrites

The methods used by Miller to construct his example S$ has also been applied to get a modification D$ of S$ in [Charatonik 1979, Chapter IV, p. 230] (an outline of this construction is in [Caratonik 1977]). Below we summarize properties of this example, and recall an extension of this construction.

  1. There exists a dendrite D$ such that:
    1. each point of D$ is of order nor greater than 4$;
    2. for each n \in \{1, 2, 3, 4\}$ the set of all points of D$ which are of order n$ is dense in D$;
    3. D$ is strongly rigid;
    4. D$ is chaotic.
  2. For any two integers m$ and n$ with 3 \le m < n$ there exists a dendrite X(m,n)$ such that (see [Charatonik et al. 1996, Theorem 5.5, p. 185] and compare also [Charatonik 1999, Theorem 27, p. 24]):
    1. \mathrm{ord}\,(x, X(m,n)) \in \{1,2,m, n\}$ for each x \in X(m,n)$.
    2. Every arc in X(m,n)$ contains a point of order m$ in X(m,n)$.
    3. Each of the sets: of all end points of X(m,n)$, of all points of order m$ in X(m,n)$ and of all points of order n$ in X(m,n)$ is dense in X(m,n)$.
    4. X(m,n)$ is strongly chaotic.

    Dendrite D$ is called a modified Miller dendrite . (For a further modification of the above construction that leads to chaotic, strongly rigid, openly rigid and not strongly chaotic dendrites, see [Charatonik 2000, Theorem 3.14, p. 650].)

    Finally recall dendrites constructed in [Charatonik 1999, Examples 33 and 35, p. 28].

  3. For each natural n \ge 5$, there exists a strongly rigid and not chaotic dendrite, all points of which are of order at most n$ ([Charatonik 1999, Example 33, p. 28]).
  4. There exists a rigid dendrite which is neither chaotic nor strongly rigid ([Charatonik 1999, Example 35, p. 28]).
