A study of finite type invariants of higher-orders of classical and virtual knots
Abstract: The filtration of the original Vassiliev invariant is well
studied in view of clasper theory (e.g. Goussarov, Habiro for knots,
Stanford, Kohno for pure braids). However, for virtual knots, even
filtration of higher-order is still unclear though it is known that
the notion of virtual knots are useful to obtain classical and virtual
knot invariants. This talk is based on a joint work with Migiwa
Sakurai (arXiv: 2004.14785).
