A Quick Note On Homsets and Diagrams

Geometric Topology 2025-09-16 v2

Abstract

The homset invariant of a knot or link L with respect to an algebraic knot coloring structure X can be identified with a set of colorings of a diagram of L by elements of X via an identification of diagrammatic generators with algebraic generators. In some cases, particularly when either L or X has a high degree of symmetry, distinct homset elements can be represented by superficially similar X-colored diagrams, potentially leading to confusion. In this short note we examine and attempt to clarify this phenomenon.
