Package: braids 1.0.0
Stéphane Laurent
braids: The Braid Groups
Deals with the braid groups. Includes creation of some specific braids, group operations, free reduction, and Bronfman polynomials. Braid theory has applications in fluid mechanics and quantum physics. The code is adapted from the 'Haskell' library 'combinat', and is based on Birman and Brendle (2005) <doi:10.48550/arXiv.math/0409205>.
