  2. Braid group - Wikipedia

    en.wikipedia.org/wiki/Braid_group

    The composition of the braids σ and τ is written as στ.. The set of all braids on four strands is denoted by .The above composition of braids is indeed a group operation. . The identity element is the braid consisting of four parallel horizontal strands, and the inverse of a braid consists of that braid which "undoes" whatever the first braid did, which is obtained by flipping a diagram ...

    Braids, Links, and Mapping Class Groups is a mathematical monograph on braid groups and their applications in low-dimensional topology.It was written by Joan Birman, based on lecture notes by James W. Cannon, [1] and published in 1974 by the Princeton University Press and University of Tokyo Press, as volume 82 of the book series Annals of Mathematics Studies.

  4. Braid (hairstyle) - Wikipedia

    en.wikipedia.org/wiki/Braid_(hairstyle)

    French braid: A classic braid where hair is braided in three strands, incorporating additional hair into each section. Senegalese Twists: Also known as rope twists, this style involves two-strand twists with hair extensions. Feed-in Braids: Braids that start thin and gradually get thicker, offering a natural and less bulky look.

  5. Turk's head knot - Wikipedia

    en.wikipedia.org/wiki/Turk's_head_knot

    The knot may be tied with a single strand if and only if the two numbers are co-prime. For example, 3 lead × 5 bights (3×5), or 5 lead × 7 bights (5×7). There are three general groupings of Turk's head knots: Narrow, where the number of leads is two or more less than the number of bights (3×5, or 3×7).

    A braid. A braid (also referred to as a plait; / p l æ t /) is a complex structure or pattern formed by interlacing three or more strands of flexible material such as textile yarns, wire, or hair. [1] The simplest and most common version is a flat, solid, three-stranded structure.

    en.wikipedia.org/wiki/Braided_monoidal_category

    For along with the commutativity constraint to be called a braided monoidal category, the following hexagonal diagrams must commute for all objects ,,. Here α {\displaystyle \alpha } is the associativity isomorphism coming from the monoidal structure on C {\displaystyle {\mathcal {C}}} :

  9. Markov theorem - Wikipedia

    en.wikipedia.org/wiki/Markov_theorem

    Braids are algebraic objects described by diagrams; the relation to topology is given by Alexander's theorem which states that every knot or link in three-dimensional Euclidean space is the closure of a braid.
