Linearized chord diagrams and an upper bound for Vassiliev invariants


Recently, Stoimenow [J. Knot Th. Ram. 7 (1998), 93-114] gave an upper bound on the dimension dn of the space of order n Vassiliev knot invariants, by considering chord diagrams of a certain type. We present a simpler argument which gives a better bound on the number of these chord diagrams, and hence on dn.
