6.129 The circles M\u2217 \u03b8 . Fig. 6.130 Projection of Klein Bottle Example 6.25. We define m\u03b8 to be the half-flip isotopy in R3 + of the circle M0 \u2286R3 + parameterized by 0 \u2264\u03b8 \u22642\u03c0 where m\u03b8 is the circle M0 rotated positively about the x-axis by an angle of \u03b8\/2. These circles are called meridians of the Klein bottle. This rotation will be considered positive if, looking down the x-axis, it appears to be counterclockwise.<\/p>\n

As a set m0 = m2\u03c0. We define M\u03b8 = i\u03b8(m\u03b8) \u2286H3 \u03b8. We take the standard knotting of the Klein bottle to be: K2 = S\u03b8=2\u03c0 \u03b8=0 M\u03b8. Figure 6.129 shows the projection of a number of the meridians of K2. For each \u03b8, M\u03b8 \u2286H3 \u03b8 \u2286R4 and M \u2217 \u03b8 \u2286H2 \u03b8 \u2286R3. Circle M \u2217 0 projects to a circle. The other circles M\u03b8 project to ellipses with M \u2217 \u03c0 projecting to a line segment.<\/p>\n

The resulting projection K2 \u2217is shown in Figure 6.130. The crossing set of K2 \u2217is a line segment, M \u2217 \u03c0 with each endpoint a branch point. Figures 6.131 and 6.132 give more detail for the w-coordinate, using wire-frame coding. Fig. 6.131 Projection of Klein Bottle with wire-frame coding. Fig. 6.132 Figure 6.131 from a lower viewpoint. We used a rotation of angle \u03b8\/2 for 0 \u2264\u03b8 \u22642\u03c0 but if we rotate by an angle of \u2212\u03b8\/2 (that is a negative rather than positive half-flip), we get a different isotopy, m\u2032 \u03b8 and a corresponding different knotting K\u2032.<\/p>\n

We will show in Section 7.3 that these are isotopic. High-Dimensional Knotting: An Illustrated Guide Remark 6.4. In topological terms one can say: \u201cthe Klein bottle is ob- tained as a connected sum of two proper M\u00a8obius bands\u201d. We can visualize this using K2 \u2217as follows. Express the circle m\u03b8 is the union of two semi-circles with common endpoints: A = {(r, \u03b8, z, w) \u2208m\u03b8 : 2 \u2264r \u22643} and B = {(r, \u03b8, z, w) \u2208m\u03b8 : 1 \u2264r \u22643}, see Figure 6.133.<\/p>\n

Editor-in-charge: Louis H. Kauffman (Univ. of Illinois, Chicago) The Series on Knots and Everything: is a book series polarized around the theory of knots. Volume 1 in the series is Louis H Kauffman\u2019s Knots and Physics. One purpose of this series is to continue the exploration of many of the themes indicated in Volume 1. These themes reach out beyond knot theory into physics, mathematics, logic, linguistics, philosophy, biology and practical experience. All of these outreaches have relations with knot theory when knot theory is regarded as a pivot or meeting place for apparently separate ideas.<\/p>\n

Knots act as such a pivotal place. We do not fully understand why this is so. The series represents stages in the exploration of this nexus. Details of the titles in this series to date give a picture of the enterprise. Published: Vol. 79: High-Dimensional Knotting: An Illustrated Guide by D.
