Evolution of Scale-invariant Inhomogeneities in Standard Cosmology
Elcio Abdalla, Roya Mohayaee
It is shown that density fluctuations obey a scaling law in an open Friedmann universe. In a flat universe, the fluctuations are not scale-invariant. We compute the growth rate of…

Scale-invariant Perturbation of the Friedmann Universe
E. Abdalla, Roya Mohayaee
We use de Vaucouleurs' power-law density-distance relation, to study a hierarchical perturbation of the Friedmann universe. We solve the Einstein equation and obtain the density co…

Two-dimensional Quantum Field Theory, examples and applications
E. Abdalla
The main principles of two-dimensional quantum field theories, in particular two-dimensional QCD and gravity are reviewed. We study non-perturbative aspects of these theories which…
