The two-fixed-points-or-high-periodic-points conjecture for torus homeomorphisms

About 19 years old · traced to

Let F ⁣:T2→T2F\colon \mathbb{T}^2\to\mathbb{T}^2 be a homeomorphism homotopic to the identity and satisfying the curve intersection property. Under these hypotheses, either FF has two fixed points or FF has periodic points of arbitrarily high periods.

Two-fixed-points-or-high-periodic-points conjecture. Either FF has two fixed points or FF has periodic points of arbitrarily high periods.

This is presented as the expected strengthening of the preceding theorem: when the curve intersection property holds, a torus homeomorphism either has rich periodic dynamics or, in the fixed-point case, should have a second fixed point. The supplied text does not establish the assertion, and its resolution is not specified.
