The Bondi-Metzner-Sachs group B is the common asymptotic group of all asymptotically at (lorentzian) space-times, and is the best candidate for the universal symmetry group of General Relativity. However, in quantum gravity, complexi ed or euclidean versions of General Relativity are frequently considered. McCarthy has shown …
