The knottedness and chirality of the trefoil page 2

Filed under: knots,Mathematics — Rob @ 2:31 pm

This is an excerpt from a larger work found at the left under the categories mathematics, knots.

Basically what I do is look at two starting/ending diagrams of the trefoil which have the same shape but could have different crossings. That is, at corresponding crossings instead of one arc being over another the arcs could be reversed and an arc would be under another.

Then if the diagrams are to be equivalent there must be a sequence of the three basic knot moves leading from one to the other.

However, I start with a different space and take the diagrams out of the space they are in. I create a more basic space of “locations of location”. Locations are then no longer at fixed positions but are able to move.

Then the diagrams move to fill in the voids left by their counterparts.

Then can I form any unknotted or mirror image knots? If it turns out I can’t then the trefoil is knotted and chiral.

It is also possible that the ar and bs joining pairs can move past one another. This is because they are parts. We could have a D-sharing forming and then an ar or bs joining could move through the sharing, then the D-sharing can reform and we can move one joining pair past another, if we allow another level to the geometry. Then it might be possible to have a different shape appearing. This can be some future work.
