On eigenvalues of double branched covers

Kouki Sato

For a given knot, we study the minimal number of positive eigenvalues of the double branched cover over spanning surfaces for the knot. The value gives a lower bound for various ge…

A full-twist inequality for the $ν^{+}$ -invariant

Kouki Sato

Hom and Wu introduced a knot concordance invariant called $ν^{+}$ , which dominates many concordance invariants derived from Heegaard Floer homology. In this paper, we give a full-twi…
