• General relativity: literature request on mixture theory

    From pglpm@21:1/5 to All on Sun May 25 07:57:17 2025
    Hi everyone,

    Thankful to anyone who can share literature references (that you deem important) about the theory of mixtures, e.g. fluid mixtures, in general relativity.

    Examples:
    - Kodama, Sasaki, https://doi.org/10.1143/PTPS.78.1
    - Giovannini, https://doi.org/10.1016/j.physletb.2005.07.013

    What I'm specifically interested about is the relationship between the energy-momentum tensor of a mixture and those of the constituents. The
    works above simply take the sum of the constituent energy-momentum
    tensors, which is not really what's done in the Newtonian theory of
    mixtures, and they don't focus on the relativistic theory of mixtures in itself.

    Probably a bit niche, but I thank you for any material you may have.
    Luca
