IISER MOHALI

Abstract: The goal of this talk is to discuss Hamiltonian methods for gaugetheories in the context of asymptotic symmetries, with gravity beingthe key focus. With a brief overview of the role of asymptoticsymmetries in scattering processes and infrared physics, I willoutline the different forms of Hamiltonian dynamics proposed by Dirac.I will then demonstrate how asymptotic symmetries in gravity, namelythe BMS symmetry, may be canonically described within the (3+1) ADMHamiltonian formulation or Dirac's "instant form" approach, as well asthe light-cone formalism based on the "front form" approach. Finally,I will comment on the implications of our results for theinitial-value problem of GR, gravitational radiation, and flat spaceholography.\n\nMeeting ID: 914 1547 7133\nPasscode: 389205\n
