The Dihedral Genus of a Knot

Patricia Cahn, Alexandra Kjuchukova

Let $K \subset S^{3}$ be a Fox $p$ -colored knot and assume $K$ bounds a locally flat surface $S \subset B^{4}$ over which the given $p$ -coloring extends. This coloring of $S$ induces a d…

Computing Ribbon Obstructions for Colored Knots

Patricia Cahn, Alexandra Kjuchukova

Kjuchukova's $Ξ_{p}$ invariant gives a ribbon obstruction for Fox $p$ -colored knots. The invariant is derived from dihedral branched covers of 4-manifolds, and is needed to calculate…
