Komar Mass - Komar Mass As Surface Integral - General Stationary Metric

General Stationary Metric

We also wish to give the general result for expressing the Komar mass as a surface integral.

The formula for the Komar mass in terms of the metric and its Killing vector is (Wald, 1984, pg 289, formula 11.2.9)

where are the Levi-civita symbols
is the Killing vector of our stationary metric, normalized so that at infinity.

The surface integral above is interpreted as the "natural" integral of a two form over a manifold.

As mentioned previously, if none of the metric coefficients are functions of time,

Famous quotes containing the words general and/or stationary:

    “The general public is easy. You don’t have to answer to anyone; and as long as you follow the rules of your profession, you needn’t worry about the consequences. But the problem with the powerful and rich is that when they are sick, they really want their doctors to cure them.”
    —Molière [Jean Baptiste Poquelin] (1622–1673)

    “It is the dissenter, the theorist, the aspirant, who is quitting this ancient domain to embark on seas of adventure, who engages our interest. Omitting then for the present all notice of the stationary class, we shall find that the movement party divides itself into two classes, the actors, and the students.”
    —Ralph Waldo Emerson (1803–1882)
