Line 1: Line 1:
Bijection between knots on a circle and knots on a (long) line.
'''Claim 1''': There is a bijection between round knots (i.e. knots on a circle) and long knots (i.e. knots on a long line):
: <math>\mathcal{K}(\bigcirc)=\mathcal{K}(|)</math>


The long like is an Abelian monoid.
'''Claim 2''': <math>\mathcal{K}(|)</math> is an abelian monoid.

''Remark'': I think it's worth checking that the map from circle to line is independent of the choice of point to 'open up' and the path we 'pull out' the two ends after cutting. However it is indeed independent.

Claim 1: There is a bijection between round knots (i.e. knots on a circle) and long knots (i.e. knots on a long line):

Claim 2: is an abelian monoid.

Remark: I think it's worth checking that the map from circle to line is independent of the choice of point to 'open up' and the path we 'pull out' the two ends after cutting. However it is indeed independent.
