A new construction of counterexamples to the bounded orbit conjecture

The bounded orbit conjecture says that every homeomorphism on the plane with each of its orbits being bounded must have a fixed point. Brouwer's translation theorem asserts that the conjecture is true for orientation preserving homeomorphisms, but Boyles' counterexample shows that it is false for the orientation reversing case. In this paper, we give a more comprehensible construction of counterexamples to the conjecture. Roughly speaking, we construct an orientation reversing homeomorphisms f on the square J²=-1, 1² with (x, f) =\ (-1. 1), (1, 1) \ and (x, f) =\ (-1. -1), (1, -1) \ for each x (-1, 1) ². Then by a semi-conjugacy defined by pushing an appropriate part of J² into (-1, 1) ², f induces a homeomorphism on the plane, which is a counterexample.
