From what I gather, those are Wilson loops applied to a QFT upon which you've performed a Wick rotation. I suppose they give you topological invariants of the corresponding thermal theory? What I had in mind was a discrepancy in the trace -- a Wilson loop is functional if the perimeter measure is correct, whereas a Polyakov loop implies the area between confined states is what's needed (fuzzy re-hash). I think it's related to confinement and chiral symmetry breaking. I'll follow up on what you've mentioned. I shouldn't have asked the last leading question, Glueballs. Would you explain what about it makes you think it "is considered to be the toughest problem around concerning physics?" I thought it was the conceptual or theoretical mathematical description of what has been pretty well established physically. So the back and forth between Physico-Mathematics, Mathematical-Physics; it does exist! Link to comment Share on other sites More sharing options...
