| On the definition of mass and center of mass of isolated systems in Newtonian gravity and general relativity |
| Speaker: | Carla Cederbaum (Universität Tübingen) |
| Abstract: | Isolated gravitating systems such as stars, black holes or galaxies play an
important role both in Newton's theory of gravity(NG)
and in general relativity (GR). While the definition of mass and center of mass via
the mass density is straightforward in NG, GR knows several
promising approaches. The most important definitions of center of mass in GR go back
to Beig and O Murchadha/Arnowitt, Deser and Misner
(BM/ADM) as well as to Huisken and Yau (HY). Under certain assumptions on the
asymptotic decay, the BM/ADM and the HY centers coincide (Huang,
Metzger-Eichmair, Nerz). However, both notions subtly depend on the chosen
asymptotic coordinates; in particular, we will
present an explicit example in which both centers diverge and a corresponding example in NG (C-Nerz). Moreover, we will relate the
Newtonian and the relativistic centers with the help of the Newtonian limit. |
