Knot group epimorphism from a prime knot
The knot group of a knot $K$ is the fundamental group of the knot complement $\pi_{1} (S^{3} \backslash K )$ (sometimes denoted $\pi_{1} (K)$ ).
Let $f: \pi_{1} (K) \rightarrow \pi_{1} (L) $ be a kno …

The knot group of a prime knot
The fundamental group of a knot $K$ (otherwise known as the knot group) is the fundamental group of the knot complement $S^{3} \backslash K $ in $S^{3} $.
