Description
Considering the simple case of 2D massless scalar fields in the light-cone formulation, we shall explore several subtleties that arise when setting up the canonical formulation on a single or on two intersecting null hyperplanes. Our analysis is particularly well-suited for a consistent treatment of zero modes, matching conditions (akin to the antipodal map for asymptotic symmetries), and infinite-dimensional global and conformal symmetries. We shall also comment on some aspects of the light-cone formulation that are relevant to Carrollian field theories, which have garnered attention in recent years in the context of flat-space holography. This talk is based on Arxiv:2401.14873 and some ongoing works.
