1. 1. The Hawking mass for ellipsoidal 2-surfaces in Minkowski and Schwarzschild spacetimes

   Magister-uppsats, Matematiska institutionen

   Författare :Daniel Hansevi; [2008]
   Nyckelord :Hawking mass; Quasi-local mass; General relativity; Ellipsoidal surface;

   Sammanfattning : In general relativity, the nature of mass is non-local. However, an appropriate def-inition of mass at a quasi-local level could give a more detailed characterization ofthe gravitational field around massive bodies. Several attempts have been made tofind such a definition. One of the candidates is the Hawking mass. LÄS MER

3. 2. Hawkingmassa i Kerr-rumtid

   Uppsats för yrkesexamina på grundnivå, Matematiska institutionen

   Författare :Jonas Jonsson Holm; [2004]
   Nyckelord :Applied mathematics; Hawking mass; black holes; quasi-local mass; Newman-Penrose formalism; Tillämpad matematik;

   Sammanfattning : In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. LÄS MER
