WebThe graph theorist often removes a crossing in the plane by making it into a knot theorist’s crossing, thereby indicating a particular embedding of the graph in three-dimensional space. This is just what we do not do with our virtual knot crossings, for then they would be indistinct from classical crossings. The virtual crossings are not there. WebIf you look at the graph of a trefoil knot you can see there can't be any polar equation for it because the mapping from θ to r is not one-to-one. The best you could do is a parametric equation in polar coords, which would …
