Smooth and topological almost concordance

Matthias Nagel, Patrick Orson, JungHwan Park +1

We investigate the disparity between smooth and topological almost concordance of knots in general 3-manifolds Y. Almost concordance is defined by considering knots in Y modulo con…

Milnor's triple linking numbers and derivatives of genus three knots

JungHwan Park

A derivative of an algebraically slice knot $K$ is an oriented link disjointly embedded in a Seifert surface of $K$ such that its homology class forms a basis for a metabolizer $H$ …

Inequality on $t_{ν} (K)$ defined by Livingston and Naik and its applications

JungHwan Park

Let $D_{+} (K, t)$ denote the positive $t$ -twisted double of $K$ . For a fixed integer-valued additive concordance invariant $ν$ that bounds the smooth four genus of a knot and determin…
