Séminaire
DIERIGL Markus (Université de Munich)
Global Symmetries, Dualities, and Bordisms

(Théorie des Interactions Fondamentales)


Sommaire:

In this talk I will summarize how duality symmetries of supergravity models can potentially lead to global symmetries. These are associated to deformation classes of spaces with non-trivial duality bundle and classified by so-called bordism groups. Since global symmetries are not allowed for consistent theories of quantum gravity, there need to exist certain objects that break these global symmetries. We will discuss S-duality for type IIB supergravity as well as U-duality for maximal 8d supergravities and explore the necessary symmetry-breaking objects in the various setups.
