On the stabilization of the Friedmann Big Bang by the shear stresses
The window is found in the space of the free parameters of the theory of viscoelastic matter for which the Friedmann singularity is stable. Under stability we mean that in the presence of the shear stresses the \textit{generic} solution of the equations of relativistic gravity possessing the isotropic, homogeneous and thermally equilibrated cosmological singularity exists.
