Large Gauge Transformation and Little Group for Soft Photons

Abstract

In this talk, the speaker will discuss the algebraic structure of the large gauge transformation (LGT) in quantum electrodynamics (QED). It implies the extension of LGT taking both electric and magnetic soft photon effects into account. He suggests that this may be relevant to the little group around the null infinity.
