Abstract

A real-valued invariant of (closed) braids, called the twist number, is introduced and studied. This invariant is effectively computable and has clear geometric sense. As a functional on the braid group, the twist number is a pseudocharacter (i.e., a function that is “almost” a homomorphism). It is closely related to Dehornoy’s ordering (and to all Thurston… (More)
