WebbSkein relations are a mathematical tool used to study knots.A central question in the mathematical theory of knots is whether two knot diagrams represent the same knot. One way to answer the question is using knot polynomials, which are invariants of the knot.If two diagrams have different polynomials, they represent different knots.In general, the … WebbJul 31, 2016 - This Pin was discovered by Chase Crawford.

The simplest example of a knot is the unknot, which is just any knot equivalent to a simple circle in S3, that is, any knot which is \not knotted" and thus can be \untied." Any knot diagram without any crossings is an unknot. Some unknots are represented below. … godinger hotel coffee set

A bridge in a knot diagram is an arc that is the overpass in at least one crossing.. The bridge number, b (K) b(K) of a knot K K is the minimum number of bridges occurring in a diagram of the knot.. By convention the unknot has bridge number equal to 1 1..
