Mutation, surface graphs, and alternating links in surfaces

Hans U. Boden, Zsuzsanna Dancso, Damian J. Lin +1

In this paper, we study alternating links in thickened surfaces in terms of the lattices of integer flows on their Tait graphs. We use this approach to give a short proof of the fi…

Mock Seifert matrices and unoriented algebraic concordance

Hans U. Boden, Homayun Karimi

A mock Seifert matrix is an integral square matrix representing the Gordon-Litherland form of a pair $(K, F)$ , where $K$ is a knot in a thickened surface and $F$ is an unoriented sp…

Examples of homology 3-spheres whose Chern-Simons function is not Morse-Bott

Hans U Boden, Christopher Herald, Paul Kirk

We construct two homology 3-spheres for which the (unperturbed) $S U (2)$ Chern-Simons function is not Morse-Bott. In one case, there is a degenerate isolated critical point. In the…
