WebKnots Knot diagrams Given K ˆR3, consider a projection ˇ: R3!R2. p 2ˇ(K) is a singular (double) point if jˇ 1(p)j>1 (= 2). We want regular projections: Intuitively. nitely many double points no cusps, tangencies, triple (or higher) points De nition A projection is regular if it has: nitely many singular points all are transpose double ... WebDefinition 1. A knot is a loop in 3–space without self-intersections. Considering particularly complicated knots in this form can be extremely dif- ficult, so ideally we would like a …

Web1.1 Knot Theory Knot theory is the study of mathematical knots, structures that are embedded in three-dimensional space. These are not the same knots that you would see in your shoelaces or on a boat. Mathematical knots are created when the two ends of the string are permanently joined together. Example: An example of a knot is the Unknot, or ... WebHandbook of Knot Theory - William Menasco 2005-08-02 This book is a survey of current topics in the mathematical theory of knots. For a mathematician, a knot is a closed loop in 3-dimensional space: imagine knotting an extension cord and then closing it up by inserting its plug into its outlet. Knot theory is of central importance in pure and ...
