We develop a general formalism to determine the statistical equilibrium states of self-
gravitating systems in general relativity and complete previous works on the subject. Our …

The general analytical solution for the static spherically symmetric metric supported by a
perfect fluid with isothermal (proportional) equation-of-state p= wρ is not known at the time of …

We argued previously that the well-known equation for hydrostatic equilibrium in a static
spherically symmetric spacetime supported by an isotropic perfect fluid should be called the …
