Logarithmic angle-dependent gauge transformations at null infinity

Abstract Logarithmic angle-dependent gauge transformations are symmetries of electromagnetism that are canonically conjugate to the standard O 1 $$ \mathcal{O}(1) $$ angle-dependent u(1) transformations. They were exhibited a few years ago at spatial infinity. In this paper, we derive their explicit...
