Project Summary

The importance of symmetries in physics research cannot be overemphasized. In particular, the exceptional success of general relativity in describing the nature of gravitational interaction, as confirmed in numerous experiments, is based on thorough understanding of the underlying symmetries. However, there exists strong theoretical evidence that in order to describe physical phenomena in the quantumgravity regime one has to allow for more general symmetry structures. The proposed research aims at advancing our understanding of generalized symmetry principles relevant for a theory of quantum gravity as one of the building blocks of so far elusive theory. Using a set of models motivated by string theory as proxies for quantum gravity we shall investigate relevant symmetry structures and their physical implications. We expect that our result will contribute both to the more formal, mathematical understanding of generalized symmetries and to the development of concrete physical description of quantum gravity related phenomena.
