Title: “Non-Symmetries and 2-Dimensional QCD” ?Abstract :

We will review the subject of “non-symmetries’’ or “defect symmetries.” We will argue that massless two dimensional QCD admits exponentially many such symmetries and we use them to prove deconfinement as well as to compute exactly the tension of thestring in the small mass limit.
