Knot group
WebA mathematical knot K is de ned to be a topological imbedding of the circle into the 3-dimensional Euclidean space. Conceptually, a knot can be pictured as knotted shoe lace with both ends glued together. Two knots are said to be equivalent if they can be continuously deformed into each other. WebJul 12, 2024 · Let $K$ be the knot and $G=\pi_1 (S^3-K)$ its knot group. The first homology group $H_1 (S^3-K)$ is isomorphic to the abelianization of $G$, hence it is isomorphic to $G/G^ { (1)}$ where $G^ { (1)}$ is the first commutator subgroup. One can check that this is isomorphic to $\mathbb {Z}$ (for instance, via the Wirtinger presentation).
