In bankruptcy 6, we describe the idea that of braid equivalence from the topological standpoint. this may lead us to a brand new suggestion braid homotopy that's mentioned absolutely within the subsequent bankruptcy. As simply pointed out, in bankruptcy 7, we will talk about the variation among braid equivalence and braid homotopy. additionally during this bankruptcy, we outline a homotopy braid invariant that seems to be the so-called Milnor quantity. bankruptcy eight is a short evaluation of knot thought, together with Alexander's theorem. whereas, Chapters nine is dedicated to Markov's theorem, which permits the applying of this concept to different fields. This used to be one of many motivations Artin had in brain whilst he all started learning braid idea. In bankruptcy 10, we speak about the first purposes of braid concept to knot concept, together with the creation of crucial invariants of knot thought, the Alexander polynomial and the Jones polynomial. In bankruptcy eleven, encouraged by means of Dirac's string challenge, the standard braid crew is generalized to the braid teams of assorted surfaces. We talk about those teams from an intuitive and diagrammatic standpoint. within the final brief bankruptcy 12, we current with out facts one theorem, as a result of Gorin and Lin [GoL] , that could be a dazzling program of braid concept to the speculation of algebraic equations.
