Distinct Minkowski Spaces from BMS Supertranslations.

Friedrich Schöller

These notes provide a smooth and everywhere well-defined extension of BMS supertranslations into the bulk of Minkowski space. The supertranslations lead to physically distinct spacetimes, all isometric to Minkowski space. This construction is in contrast to the often used, non-smooth BMS transformations that appear in a gauge fixed description of the theory.
