Non-spherical sources of Schwarzschild space-time
J. L. Hernández-Pastora, L. Herrera
While it is known that any spherical fluid distribution may only source the spherically symmetric Schwarzschild space-time, the inverse is not true. Thus, in this manuscript, we fi…

Complexity and simplicity of self-gravitating fluids
L. Herrera
We review a recently proposed definition of complexity of the structure of self--gravitating fluids \cite{ch1}, and the criterium to define the simplest mode of their evolution. We…

Expansion-free dissipative fluid spheres: Analytical models
L. Herrera, A. Di Prisco, J. Ospino
We search exact analytical solutions of spherically symmetric dissipative fluid distributions satisfying the vanishing expansion condition (vanishing expansion scalar ). To do s…
