Asymptotics with a positive cosmological constant: I. Basic framework

The asymptotic structure of the gravitational field of isolated systems has been analyzed in great detail in the case when the cosmological constant

is zero. The resulting framework lies at the foundation of research in diverse areas in gravitational science. Examples include: i) positive energy theorems in geometric analysis; ii) the coordinate invariant characterization of gravitational waves in full, non-linear general relativity; iii) computations of the energy-momentum emission in gravitational collapse and binary mergers in numerical relativity and relativistic astrophysics; and iv) constructions of asymptotic Hilbert spaces to calculate
