= Braid groups
{wiki=Braid_groups}
Braid groups are a fundamental concept in algebraic topology and group theory. They arise from the study of braids, which can be visualized as strands of string intertwined in a specific manner. \#\#\# Definition The braid group \\( B_n \\) consists of equivalence classes of braids with \\( n \\) strands. Each braid can be represented as a series of points in a plane, where strands are allowed to cross over each other but cannot break or end.
