Hamiltonian treatment of asymptotic symmetries in gauge theories — •Roberto Tanzi — University of Bremen, Center of Applied Space Technology and Microgravity (ZARM), 28359 Bremen

Asymptotic symmetries are an important feature of gravity (where they give rise to the BMS group), of electromagnetism, and of other gauge theories. The interest in this topic has increased in the last few years, in particular after it has been conjectured by Hawking, Perry, and Strominger that it could be related to the solution of the long-standing information loss paradox.

I will discuss the Hamiltonian approach to asymptotic symmetries in gauge theories (first pursued by Henneaux and Troessaert), with a particular focus on non-abelian gauge theories.
