Title: Web diagrams and realization of
Vassiliev invariants by knots
Abstract:
Recently as a joint work with Kouki Taniyama and
Shuji Yamada, the following result is obtained by using
local moves of knots.
There exist infinitely many unknotting number one knots,
all of whose Vassiliev invariants of order at most n coincide
with those of K for any knot K.
In this talk, I will explain the way of constructing knots with
the same Vassiliev invariants of order at most n and give
another proof of this result by using Web diagrams.
