Stably slice disks of links
Anthony Conway, Matthias Nagel
We define the stabilizing number of a knot as the minimal number of connected summands required for to bound a nullh…
Triple linking numbers and surface systems
Christopher William Davis, Matthias Nagel, Patrick Orson +1
We give a refined value group for the collection of triple linking numbers of links in the 3-sphere. Given two links with the same pairwise linking numbers we show that they have t…
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…
Representation varieties detect essential surfaces
Stefan Friedl, Takahiro Kitayama, Matthias Nagel
Extending Culler-Shalen theory, Hara and the second author presented a way to construct certain kinds of branched surfaces in a -manifold from an ideal point of a curve in the $…
A note on the existence of essential tribranched surfaces
Stefan Friedl, Takahiro Kitayama, Matthias Nagel
The second author and Hara introduced the notion of an essential tribranched surface that is a generalisation of the notion of an essential embedded surface in a 3-manifold. We sho…
Twisted Reidemeister torsion and the Thurston norm: graph manifolds and finite representations
Stefan Friedl, Matthias Nagel
We show that the Thurston norm of any irreducible 3-manifold can be detected using twisted Reidemeister torsions corresponding to integral representations and also corresponding to…
