Let $K$ be an amphicheiral knot, and let $\Delta_K$ be its Alexander polynomial. Stoimenow's sign conjecture. The sign of the leading coefficient of $\Delta_K$ is … The conjecture…

Let $K$ be an amphicheiral knot, and let $\Delta_K$ denote its Alexander polynomial; equivalently, consider the leading coefficient of its Conway polynomial. Stoimenow's square lea…

Let $K$ be an amphicheiral knot, and let $C_K(z)$ denote its Conway polynomial. Conant's integral splitting conjecture. For some $\phi\in\mathbb Z[z]$, one has … The conjecture str…
