Quandle coloring quivers (Sam Nelson, CMC)
Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesGiven a finite quandle $X$, a set $S \subset \mathrm{Hom}(X,X)$ of quandle endomoprhisms, and an oriented knot or link $L$, we construct a quiver-valued invariant of oriented knots and links. This quiver categorifies the quandle counting invariant in the most literal sense and can be used to define many enhancements of the counting invariant. This […]
