Abstract.Using the universal cover of the Möbius band, we construct an example as described in the title which answers a question of K. Kuperberg.Krystyna Kuperberg has recently asked whether there exists an orientation reversing homeomorphism of the plane with an invariant pseudo-arc. We provide a positive answer to this question. Her question was apparently motivated by her recent work [4] on fixed points and orientation reversing homeomorphisms.Most embeddings of the pseudo-arc in the plane appear to admit very few homeomorphism which extend to homeomorphisms of the plane. For many embeddings, e.g., the "standard" embedding with two accessible composants [7], one can show that every extendable homeomorphism must preserve orientation of the plane. Thus our example depends on choosing the correct embedding of the pseudo-arc.Since there has been significant recent interest in the dynamics of homeomorphisms of the pseudo-arc and in which homeomorphisms of the pseudo-arc extend to homeomorphisms of the plane, it is worth noting that the example we construct has fairly elementary dynamics. There are two fixed points of the pseudo-arc under our homeomorphism.Every other point of the psuedo-arc is repelled from one of these fixed points and attracted to the other. One can construct examples with more interesting dynamics.We conclude with some observations about prime ends, accessible points, and extendable homeomorphisms.
The constructionOur main result is the following Theorem. There exists an orientation reversins homeomorphism of the plane with an invariant pseudo-arc.Our proof is constructive. The construction can be outlined in the following few steps and observations. -
