Correspondence conjecture between horizontal Goodman surgery and veering triangulations
Correspondence conjecture between horizontal Goodman surgery and veering triangulations
A veering triangulation on an oriented -manifold determines a transitive pseudo-Anosov flow on a closed oriented -manifold , and a transitive pseudo-Anosov flow on a closed oriented -manifold determines a veering triangulation after removing a collection of closed orbits . A horizontal surgery curve is a curve satisfying the relevant horizontal-surgery conditions for the corresponding flow or triangulation. Correspondence conjecture. For every veering triangulation on , every horizontal surgery curve for is isotopic to one for , and
Conversely, for every transitive pseudo-Anosov flow and a suitable collection of closed orbits, every horizontal surgery curve for is isotopic to one for , and
Here has the appropriate sign for the horizontal surgery. The conjecture would identify the dynamical and combinatorial surgery operations exactly, strengthening the correspondence between veering triangulations and pseudo-Anosov flows; the source does not state that any part of this formulation is proved.
