Realization of Weyl (local conformal) Symmetry
In my current research I am pursuing topics concerning realization of symmetries when they arise in unexpected ways; for example, in models of cosmic inflation. Particularly intriguing is the possibility that Weyl symmetry is present, but the expected Noether charge and current vanish identically. My goal is to understand and clarify this unexpected realization of symmetry.
