Quasi-local variables, non-linear perturbations and back-reaction in spherically symmetric spacetimes
Roberto A Sussman
We introduce a quasi-local integral functional and scalar quasi-local variables to examine a wide class of spherically symmetric inhomogeneous spacetimes that generalize the Lemait…

A dynamical system approach to inhomogeneous dust solutions
Roberto A. Sussman
We examine numerically and qualitatively the Lema\^ıtre--Tolman--Bondi (LTB) inhomogeneous dust solutions as a 3--dimensional dynamical system characterized by six critical points.…

Adiabatic models of the cosmological radiative era
Roberto A. Sussman, Mustapha Ishak
We consider a generalization of the Lemaitre-Tolman-Bondi (LTB) solutions by keeping the LTB metric but replacing its dust matter source by an imperfect fluid with anisotropic pres…
