Almost immediately he found that the trace or \u201cMarkov\u201d property of \u03c1 allowed new link invariants to be defined and this ushered in the era of quantum topology. There has been an explosion of link and 3- manifold invariants with beautiful inter-relations, asymptotic formulae, and enchanting connections to mathematical physics: Chern-Simons theory and 2-dimensional statistical mechanics. While many sought to bend Jones\u2019 theory toward classical topological objectives, we have found that the relation between the Jones polynomial and physics allows potentially realistic models of quantum computation to be created [FKW][FLW][FKLW][F]. Unitarity, a hidden locality, and density of the Jones representation are central to computational applications. With this application in mind, we have returned to some of Jones\u2019 earliest questions about these representations and the distributions of his invariants. A few concise answers are stated here in the introduction. Question 9 of Jones in [J2] asked for the closed images of the irreducible components of his representation. We answer Jones\u2019 question, and also identified the closed images for the general SU(N) case completely.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In 1983 V.
