Use of continuous models lets us take advantage of the tools provided by calculus and, moreover, such a framework belongs to the traditional approach to modeling physical phenomena.

D. Gannress, 1984), we start by defining the Komar mass for stationary spacetimes. We then discuss field theory and introduce the Einstein–Hilbert action as a means of motivating the definition of the ADM mass. Finally, we prove the (Riemannian) positive mass theorem and the (Riemannian) Penrose inequality

F. Schweiggertfield equations, following Wald (General relativity, University of Chicago Press, 1984). We start by studying the Klein–Gordon equation, as a prototypical wave equation, and the Maxwell equations, where the issues of constraints on the initial data and gauge freedom also arise. We then sketch the pr
