How to build the Stasheff Associahedron out of a trefoil knot

The Stasheff Associahedra are a family of polytopes that seem to be ubiquitous, but in particular are strongly linked to associativity. Here are the first few: The vertices of the -dimensional associahedron are in bijection with bracketings of the word , or equivalently, with the set of planar binary trees with leaves. For example, there Continue reading How to build the Stasheff Associahedron out…
