Theoretical Study of Voids In Some Cosmological Models
Abstract
The stability of a cosmological model is considered as the equality of the density of matter everywhere in this model. But in reality the matter in the universe is concentrated within large scale structures, and on the other had voids are formed. In this work a theoretical study about formation of voids in some stable cosmological models. The self-consistent model formulated in the framework of the Generalized Field Theory , the standard model built in the General Theory of Relativity, and Saez and de Juan model constructed in the background of Møller Tetrad Theory of gravitation, are used in this study. A comparison between the results of these models has been done. It is clear that in all models the formations of voids, as complimentary part of formation of large scale structures, depend on a parameter ( ɛ ) . This parameter depends on the model itself.
