Abstract
After providing a definition of asymptotic flatness, we introduce the global quantities that one may associate to the spacetime or to each slice of the 3 + 1 foliation: the ADM mass, the ADM linear momentum, the total angular momentum, the Komar mass and the Komar angular momentum. For each of these quantities, we derive expressions in terms of the 3+1 objects and provide some concrete examples.
