Psyquandle coloring quivers

Abstract

We enhance the psyquandle counting invariant for singular knots and pseudoknots using quivers analogously to quandle coloring quivers. This enables us to extend the in-degree polynomial invariants from quandle coloring quiver theory to the case of singular knots and pseudoknots. As a side effect, we obtain biquandle coloring quivers and in-degree polynomial invariants for classical and virtual knots and links.
