Radiative phase space extensions at all orders (PRETALK for students at 15:30 h)
In the self-dual sector for Yang-Mills and gravity, I will show how to construct an extended phase space at null infinity, to all orders in the radial expansion. This formalises the symmetry origin of the infrared behaviour of these theories to all subleading orders. As a corollary, I will also derive a double copy mapping a subset of YM gauge transformations to a subset of diffeomorphisms to all orders in the transformation parameters.
