概要
In this talk, we will discuss some knot theoretic meanings of high
dimensional homotopy groups. The talk will aim to give a natural
combinatorial descprition of general homotopy groups of any dimensional
spheres using braid groups, as well as to express the general homotopy
groups of 3-spheres as certain natural sub-quotients of link groups of a
collection of links. These connections seem to address some new
questions in knot theory. The talk will aim to general audience.
