Maxwell's Demon and the Problem of Observers in General Relativity
L. Herrera
The fact that real dissipative (entropy producing) processes may be detected by non-comoving observers (tilted), in systems that appear to be isentropic for comoving observers, in…
Tilted shear-free axially symmetric fluids
L. Herrera, A. Di Prisco, J. Carot
We carry on a systematic study of the physical properties of axially symmetric fluid distributions, which appear to be geodesic, shear--free, irrotational, non--dissipative and pur…
An alternative approach to the static spherically symmetric vacuum global solution to the Einstein's equations
L. Herrera, L. Witten
We propose an alternative description of the Schwarzschild black hole based on the requirement that the solution be static not only outside the horizon but also inside it. As a con…
New definition of complexity for self-gravitating fluid distributions: The spherically symmetric, static case
L. Herrera
We put forward a new definition of complexity, for static and spherically symmetric self--gravitating systems, based on a quantity, hereafter referred to as complexity factor, that…
