Quandle coloring quivers and 2-bridge links (Q6595556)

The quandle coloring quiver, introduced by \textit{K. Cho} and \textit{S. Nelson} [Topology Appl. 268, Article ID 106908, 10 p. (2019; Zbl 1473.57007)], serves as a categorification of the quandle coloring number. This quiver invariant provides more detailed information compared to other quandle enhancements. In the paper under review, the quandle coloring quivers of 2-bridge links are computed using dihedral quandles. By applying known formulas for the quandle cocycle invariants of 2-bridge links with dihedral quandles of prime orders, these results enable the calculation of the quandle cocycle quivers for 2-bridge links.
