(LD) Such connections appeared in set theory in the 1980s and led to the discovery in 1991 of a left invariant linear order on the braid groups. Braids and self-dis

The Order on Positive Braidsociates with every positive braid a normal form consisting in a finite tree; the order of positive braids is then a lexicographical ordering for the associated trees, and one deduces that the order type of . is the ordinal ..
