Acyclic Poset Multiplihedra and their Quotients
Stefan Forcey, Ross Glew, Christopher Tapo
Two families of polytopes underlie the combinatorics of associative operations. Associahedra and multiplihedra respectively capture the information in the operation itself and in t…
Generalised wavefunction coefficients and acyclonesto-cosmohedra
Stefan Forcey, Ross Glew, Hyungrok Kim
Scattering amplitudes of theory can be encoded as the canonical form of the Stasheff associahedron. Similarly, the flat-space wavefunction coefficients of…
Counting plane arrangements via oriented matroids
Stefan Forcey
Planes are familiar mathematical objects which lie at the subtle boundary between continuous geometry and discrete combinatorics. A plane is geometrical, certainly, but the ways th…
Compactifications of phylogenetic systems and species of electrical networks
Satyan L. Devadoss, Stefan Forcey
We describe new spaces and maps. Our graphical map is a visual and numerical correspondence between spaces of circular electrical networks and circular planar split systems. When r…
Circular planar electrical networks, Split systems, and Phylogenetic networks
Stefan Forcey
We study a new invariant of circular planar electrical networks, well known to phylogeneticists: the circular split system. We use our invariant to answer some open questions about…
Phylogenetic networks as circuits with resistance distance
Stefan Forcey, Drew Scalzo
Phylogenetic networks are notoriously difficult to reconstruct. Here we suggest that it can be useful to view unknown genetic distance along edges in phylogenetic networks as analo…
