| Details: | Research over the past few years have revealed that in four dimensional asymptotically flat space time any gauge theory or theory of gravity has infinite dimensional global symmetries. These are called asymptotic symmetry or the group of large transformations. Quite surprisingly the well known soft soft factorization theorems for S-matrix elements can be thought of as the Ward identities for these symmetries. In this talk I will discuss some of the applications of this and will also discuss what new thing it teaches us about the symmetries of Yang-Mills theory and Einstein gravity in four dimensions. |
