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 ...
Box braids are a type of hair-braiding style that is predominantly popular among African people and the African diaspora. This type of hairstyle is a "protective style" (a style which can be worn for a long period of time to let natural hair grow and protect the ends of the hair) and is "boxy", consisting of square-shaped hair divisions.
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.
Spin representations can be analysed according to the following strategy: if S is a real spin representation of Spin(p, q), then its complexification is a complex spin representation of Spin(p, q); as a representation of so(p, q), it therefore extends to a complex representation of so(n, C).
Knotless Braids: A variation of box braids, starting with natural hair and gradually adding extensions, reducing scalp tension.Knotless braids do not include the knots. Crochet braids: Extensions are crocheted into cornrowed natural hair, offering a variety of styling options. French braid: A classic braid where hair is braided in three strands ...
The diagram algebra for () is deduced from the diagram algebra for () by turning rectangles into cylinders. The algebra a T L n ( δ ) {\displaystyle aTL_{n}(\delta )} is infinite-dimensional because lines can wind around the cylinder.
Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe.
1925 braiding machine in action The smallest braiding machine consists of two horn gears and three bobbins. This produces a flat, 3-strand braid. A braiding machine is a device that interlaces three or more strands of yarn or wire to create a variety of materials, including rope, reinforced hose, covered power cords, and some types of lace.
