Associahedron conjecture for mutation graphs of torus braids

Let β\beta be the (n,2)(n,2) torus braid, let Δ\Delta denote the positive half-twist, and consider the mutation graph whose vertices are equivalence classes of Demazure weaves βΔΔ\beta\cdot\Delta\to\Delta and whose edges correspond to mutations. Torus-braid associahedron conjecture. This mutation graph is the 11-skeleton of the (n1)(n-1)-dimensional associahedron. The conjecture identifies the weave mutation graph for these torus braids with the combinatorial exchange graph of the associahedron; the paper presents it as a conjectural extension of the pentagon example.
