Webinaire Cirget: «Squeezed knots»
Conférencier: Lukas Lewark, Regensberg
Résumé / Abstract: A knot is called squeezed if it is a slice of a smooth cobordism of minimal genus between a positive knot and a negative knot. Most small knots are squeezed, as are many classes of knots, such as alternating knots. However, Khovanov homology and related tools may obstruct squeezedness. This is joint work in progress with Peter Feller and Andrew Lobb.
