Stabilizer subgroups of Thompson's group F in Thompson knot theory (JAPANESE)
[ 講演概要 ]
Thompson knot theory, introduced by Vaughan Jones, is a study of knot theory using Thompson's group F.
More specifically, he defined a method of constructing a knot from an element of F, and proved that any knot can be realized in his way. This fact is called Alexander’s theorem, which is an analogy of the braid group. In this talk, we consider Thompson knot theory in terms of a relation between subgroups of F and knots obtained from their elements. In particular, we focus on stabilizer subgroups of F with respect to the natural action on the unit interval. This talk is based on joint work with Yuya Kodama (Tokyo Metropolitan University).
