Title: A positive mass theorem for static causal fermion systems
Abstract: After a short general introduction to causal fermion systems and to the positive mass theorem for asymptotically flat Riemannian manifolds, I will explain how to describe an asymptotically flat manifold by a static causal fermion system. The total mass of a static, asymptotically flat causal fermion system is defined abstractly, and it is shown that this definition reduces to the ADM mass in a certain limiting case. I will also outline the proof that for a minimizer of the causal action principle, the total mass is always non-negative. I am reporting on joint work with Andreas Platzer.
