Stability of Hawking Mass

  1. Jun 19, 2014 #1
    What is stability of Hawking Mass and how to calculate it? Any references will be appreciated. Thanks

    What is "Hawking mass"? Do you have a reference for this term? It doesn't seem to be a standard term in physics.

    Here's a couple more references.

    This one goes into more theoretical detail, and mentions several other related quantities:

    This one calculates the Hawking energy for Schwarzschild exactly, and numerically for Kerr:

    You might tell us more specifics about your interest in the Hawking energy.

    Thank you so much for the references.

    I want to know what we talk about when we talk about stability of Hawking energy?
    How can we know the Hawking energy is stable?

    What do you mean by stability?

    The above text refers to calculations done on the moduli space of a particular (lower dimensional) supergravity theory. The Hawking mass, is a *classical* quasi-local quantity.

    Stability for the former, involves (amongst other things) seeing when the (super)potential goes negative (which would destabilize the quantum vacuum) or eg if it falls of a cliff, stability for the latter is going to require more input by you, b/c its not obvious what 'stability' means in that context mathematically (the quantity may readily be negative for instance).
