**Mass and Angular Momentum in General Relativity**

by J.L. Jaramillo, E. Gourgoulhon

**Publisher**: arXiv 2010**Number of pages**: 41

**Description**:

We present an introduction to mass and angular momentum in General Relativity. After briefly reviewing energy-momentum for matter fields, first in the flat Minkowski case (Special Relativity) and then in curved spacetimes with or without symmetries, we focus on the discussion of energy-momentum for the gravitational field. We illustrate the difficulties rooted in the Equivalence Principle for defining a local energy-momentum density for the gravitational field.
