The gauge principle as applied in field theories for particle physicsrecognizes redundant degrees of freedom. Some time ago this author introduced afrustration based locally preferred structure (LPS) model of the glasstransition. Here we show that gauge freedom plays an essential role in the selforganized emergence of two temperature dependent quantities , which connect thetime dependence of the bond angle fluctuations as a given LPS approaches theglass temperature. We show that as a choice of gauge these quantitiescooperatively converge as , which is equivalent to the stretched exponentialpower observed in structural glasses. We therefore posit that gauge freedomplays a deeper role in the self-organization of this non-equilibrium system.
