Realizations of multiassociahedra via bipartite rigidity

Luis Crespo Ruiz

Let $A s s_{k} (n)$ denote the simplicial complex of $(k + 1)$ -crossing-free subsets of edges in $(2 n)$ . Here $k, n \in N$ and $n \geq 2 k + 1$ . It is conjectured that this simp…

Multitriangulations and tropical Pfaffians

Luis Crespo Ruiz, Francisco Santos

The $k$ -associahedron $A s s_{k} (n)$ is the simplicial complex of $(k + 1)$ -crossing-free subgraphs of the complete graph with vertices on a circle. Its facets are called $k$ -triangulati…

Bar-and-joint rigidity on the moment curve coincides with cofactor rigidity on a conic

Luis Crespo Ruiz, Francisco Santos

We show that, for points along the moment curve, the bar-and-joint rigidity matroid and the hyperconnectivity matroid coincide, and that both coincide with the $C_{d - 1}^{d - 2}$ -cofa…
