Asymptotic Symmetries

Asymptotic symmetries are a key concept in gravity and gauge theories and feature prominently in holographic correspondences. In this set of eight lectures I will introduce this subject, discuss examples in the context of (lower-dimensional) holography, and address some recent advances in near horizon and flat space holography. Optional homework exercises supplement the lectures.

Instructor: 

Daniel Grumiller is an Associate Professor at the Institute for Theoretical Physics, TU Wien in Vienna, Austria.  He is a physicist with particular expertise in the areas of black holes and holography.  For details of his research see his home page.
