The convex hypersurface conjecture for infinitesimal strip deformations
The convex hypersurface conjecture for infinitesimal strip deformations
For each arc , let be a minimally intersecting geodesic representative and let be a waist; with widths , define as the image of the complex of arc systems under the corresponding infinitesimal strip deformations. Convex hypersurface conjecture. There exists a choice of the representatives and waists such that, when for every , is a convex hypersurface in . The conjecture would realize the arc-system complex as part of the boundary of the convex hull of a natural discrete subset of the finite-dimensional cohomology space, before projectivization.
