### The explanation

Filed under: knots,Mathematics,the knottedness and chirality of the trefoil — Rob burchett @ 7:05 am

The explanation:

1. Crossings in R^3 or S^3 (positive space)
2. Label 1+,1-,ect. The locations of D-joinings/crossings (mixed space)
3. Place a, b at each D.
4. Move to negative space: move crossing now a sharing as we are capable of having 2 parts or more at a vertex with a and b always moving along.

1+,1-,ect. Are the specific locations in R^3 where we put the other concept sharing diagram back together.

But in the moving diagram they have some freedom. They can travel along as they are labels, reachable through moves of the diagram (that is moves are reversible) or they can stop at a specific pair of locations and the a, b pairs move on forward. This is still reversible as I can get back to this D, as I can reverse from forward motion. At the end, after I go all the way back I come back to the same location.

So 1+ and 1- label the crossing 1, where the original locations can be traced back from. I am placing the labels on specific locations. I mean that this is where the crossing is so that I can trace back to the original location which matches moves in this space then are fully reversible and take full advantage of the new freedoms. Then all these diagrams are equivalent and complete as long as we don’t cut the diagram or change the order of locations.

Then R1,R2,R3, isotopy have their equivalents as well. I have rotation of the locations, creation of labels, joinings, movements of joinings and labels through sharings. And that’s all (complete).

Let there be another diagram D(2) in R^3 and we wish to compare this to the original diagram. Move it to mixed space and then to negative space. Concept share it and one part of it moves off. If we can make a congruency between this and the other diagram in negative space then the two diagrams in positive space are also congruent.

So we need to look for a match of the labels, joinings when we simplify the diagrams.

If they are the same, then the information should be contained in one diagram. That is, movements of one diagram should be able to produce the second one. So we need to look at one diagram to see if we can produce another(using all moves available)

Let’s look at T. To cut down a lot of the moves, let’s apply a simplifying method.

Now I only need to apply S1,S2,S3 and isotopy(2) and I can obtain any diagram of T. Then reform the diagram to go back to R^3.

But the only new diagrams I can obtain will be through the application of the new moves to the T-invariant. That is all possible moves of the invariant. None yield the unknot or any achirality.

The new moves are rotation (which isn’t usually considered) and movement of labels and joinings through sharings.

### More knot diagrams

Filed under: knots,Mathematics,the knottedness and chirality of the trefoil — Rob burchett @ 7:28 pm

So here I am showing a way of seeing if the Trefoil is chiral. I take the 2 and 3 sharings out then see if I can bring them back after going through space in the different way with the 1 sharing. It turns out I can’t do that.

### Knot diagrams

Filed under: knots,Mathematics,the knottedness and chirality of the trefoil — Rob burchett @ 7:26 pm

Here I am starting to use other diagrams of a knot. These come about as we are operating in negative space. That is the new space I created with negative distance. In that space I have the ability to pass through, also to move a series of connected parts ( the knot diagram itself) and create joinings (like (a3(b2)). These combined allow me to make new moves.

### Diagram 1-The Trefoil

Filed under: knots,Mathematics,the knottedness and chirality of the trefoil — Rob burchett @ 4:11 am

This is the oriented trefoil knot in three dimensional space.

### Diagram 2-1

Filed under: knots,Mathematics,the knottedness and chirality of the trefoil — Rob burchett @ 4:09 am

So here I start with the Trefoil in three dimensional space. Then I move it to a mixed space which is described in the article on math concept sharing in this blog. I am sharing the concepts of a point and a number. We then can go back to positive space from here or on to negative space. The diagrams I draw after this are in negative space.
