On the influence of the gravitating vacuum on the dynamics of homogeneous isotropic models in gauge theories of gravity
The analysis of solutions of gravitational equations for homogeneous isotropic models in the presence of a gravitating vacuum (cosmological constant ) is given in the frame of various gauge theories of gravity on the basis of qualitative theory of dynamic systems. The equation of state of matter is given in the form of a linear dependence of the pressure p on the energy density with restriction . It is shown that regularization of metric derivatives takes place in the case of sufficiently high values of , and some are obtained which are regular in the metrics solutions for superdense gravitating systems.
