Energetic Stability of the Solutions of the Einstein Field Equations for Spherically Symmetric Liquid Shells
Jorge L. deLyra
We interpret the exact solutions previously obtained for spherically symmetric shells of liquid fluid in General Relativity in terms of the energies involved. We show that a certai…

Exact Solution of the Einstein Field Equations for a Spherical Shell of Fluid Matter
Jorge L. deLyra, Rodrigo de A. Orselli, C. E. I. Carneiro
We determine the exact solution of the Einstein field equations for the case of a spherically symmetric shell of liquid matter, characterized by an energy density which is constant…
