| 概要 | Given a finite quandle $X$, a set of quandle endomrophisms $S ¥subset ¥mathrm{Hom}(X,X)$ and a quandle 2-cocycle $¥phi$, we construct a direct graph-valued invariant of knots and link we call the quandle cocyle quiver. From this invariant we derive several polynomial enhancements of the quandle counting invariant and quandle cocycle invariant. This is joint work with my Harvey Mudd College senior thesis student Karina Cho. |
