Can knots be described mathematically?
A bow for example, it occurred to me as I took my walking boots off, is a thing of symmetry and with rules. So I wondered it it, and other knots can be described with maths.

Yes, yes they can.

It's a knotty problem and I believe some of the loose ends are still to be tied up.

Re: Can knots be described mathematically?
I suspect the answer is probably "yes", but that's just an intuitive guess. Like many people, I don't even have to consciously think when tying my shoelaces, so it's not something I've ever pondered deeply about.

Re: Can knots be described mathematically?
I believe that Thurston's geometrization conjecture states that compact 3-manifolds can be decomposed canonically into submanifolds that have geometric structures. The geometrization conjecture is an analogue for 3-manifolds of the uniformization theorem for surfaces, but I'm no expert.

Re: Can knots be described mathematically?
Knots, braids, bends, links, hitches, weaves etc. are described by d-dimensional space-curves. Their projections can be shown as 2D shadows, 2.5D knot diagrams, and 3D tubes using piece-wise cubic interpolation. Mathematical knots and links are closed 3D lines that cannot be untangled without passing lines through lines. Braids provide compact knot descriptors; bends join two ropes; hitches and binding knots are tied round posts etc.

Knot Theory
The mathematical study of knots. Knot theory considers questions such as the following:
1. Given a tangled loop of string, is it really knotted or can it, with enough ingenuity and/or luck, be untangled without having to cut it?
2. More generally, given two tangled loops of string, when are they deformable into each other?
3. Is there an effective algorithm (or any algorithm to speak of) to make these determinations?
Although there has been almost explosive growth in the number of important results proved since the discovery of the Jones polynomial, there are still many "knotty" problems and conjectures whose answers remain unknown.
etc, etc, follow links. All about topology. Why is the obvious so hard?
