Abstract
In this paper we study the relation between positive braids, their canonical normal forms and their crossing matrices. We characterize positive braids of canonical length at most 2 by their crossing matrices, but prove that for length 3 or larger this is no longer true. We characterize matrices which can be crossing matrices of braids with canonical length at most 2, answering a question by Elrifai and Morton.
