This chapter introduces the theory of braids. It explains how a knot diagram can always be expressed as the closure of a braid. Knot equivalence is then transformed into equivalence of closed braids under the braid moves and the Markov moves.

Braid lift representations of Artin's Braid Group
Journal of Knot Theory and Its Ramifications, 2000We recast the braid-lift representation of Contantinescu, Lüdde and Toppan in the language of B-type braid theory. Composing with finite dimensional representations of these braid groups we obtain various sequences of finite dimensional multi-parameter representations.

Decomposable braids as subgroups of braid groups
Transactions of the American Mathematical Society, 1975The group of all decomposable 3 3 -braids is the commutator subgroup of the group I 3 {I_3} of all 3 3 -braids which leave strand positions invariant. The group of all 2 2 -decomposable 4 4 -braids is the commutator subgroup of

Algebra and Logic, 2003
\textit{P. Dehornoy} [J. Knot Theory Ramifications 4, No. 1, 33-79 (1995; Zbl 0873.20030)] has proved that the braid group \(B(n)\) possesses a right linear order, i.e., a right linear order such that \(x\leq y\) implies \(xz\leq yz\) for any \(x,y,z\in B(n)\).

1974
The terms “braid” and “braid groups” were coined by Artin, 1925. In his paper, an n-braid appears as a specific topological object. We consider two parallel planes in euclidean 3-space which we call respectively the upper and the lower frame. We choose n distinct points U v (v = 1, ..., n) in the upper frame and denote their orthogonal projections onto

The Annals of Mathematics, 1947
In his paper 'Theorie der Z6pfe' E. Artin' presented a theory of braids based on a study of their projections on a two-dimensional plane. In the projection each strand of a braid appears as a line, vertical in general, but at certain levels two neighboring strands interchange position, one strand crossing in front of the other one.

DIAGRAM GROUPS, BRAID GROUPS, AND ORDERABILITY
Journal of Knot Theory and Its Ramifications, 2003We prove that all diagram groups (in the sense of Guba and Sapir) are left-orderable. The proof is in two steps: firstly, it is proved that all diagram groups inject in a certain braid group on infinitely many strings, and secondly, this group is then shown to be left-orderable.

In trying to establish a theory of braids, the most primitive question we may ask is, How many different (non-equivalent) braids are there?
