Abstract
The relationship between Penrose 2-surface twistors defined on infinite spheres and generators of asymptotic symmetry groups is elucidated, at both null and spatial infinity. At null infinity one finds a new elegant reformulation of the notion of a Linkage associated with generators of the B.M.S. group, and finds explicit integrals for the “Hamiltonian” flux of angular momentum given by Ashtekar and Streubel (1981). At spatial infinity one recovers conservation laws similar to those given by Ashtekar and Hansen (1978), but with additional invariance properties.
