The Links--Gould polynomial of an alternating link is alternating

Matthew Harper, Ben-Michael Kohli

Building on work of Kauffman--Saleur and earlier work of the second author, we derive a determinant formula for the Links--Gould polynomial of links. As an application, we prove a…

Vladimir Chernov, Matthew Harper, Ben-Michael Kohli

The conjectures of Low and Natario--Tod, and Penrose's question on Arnold's Problem list ask if causality in spacetimes can be formulated in terms of linking of spheres of light ra…
