Improving the Seifert inequality for the genus of a knot using the Links-Gould invariant of links

I will show how the Links-Gould invariant of links can be used to systematically improve the well known lower bound for the 3-genus of a knot known as the Seifert inequality, that is obtained from the Alexander polynomial.

For example, this allows us to straightforwardly detect genus for the Kinoshita-Terasaka/Conway pair of mutant knots, where the Seifert inequality and the Levine-Tristram signature fail to do so.

This is work in common with Guillaume Tahar.
