Self-homeomorphic dendrites

Below we present some examples of dendrites that illustrate relations between variants of self-homeomorphic properties.

  1. There is a strongly pointwise self-homeomorphic dendrite which is not of the form D_S$ for some S \subset \{3, 4, \dots, \omega\}$, see [Charatonik W.J. et al. 1994, Example 6.11, p. 232, and Fig. 4, p. 233]. Note that, according to Property 1 in 1.3.8 each dendrite D_S$ is strongly pointwise self-homeomorphic. This example shows that the opposite implication does not hold. Some additional properties of the example are shown in [Pyrih 1999b, Example 2.1, p. 152]. See Figure A.

  2. There is a strongly self-homeomorphic and pointwise self-homeomorphic dendrite which is not strongly pointwise self-homeomorphic, see [Charatonik W.J. et al. 1994, Example 6.12, p. 233].

  3. There is a strongly self-homeomorphic dendrite which is not pointwise self-homeomorphic, see [Pyrih 1999a, Example 2.1, p. 572]. Dendrites having this property are studied in [Charatonik et al. XXXXc].

    See Figure B.
