Query: On the Tensor Field Inflation in the GR Homogeneous Cosmological Model   The homogeneous cosmological model in GR is proposed, where the vacuum
energy, which can cause the inflation, is described by tensor field rather than
by commonly used in inflationary scenarios scalar field. It is shown that if
the initial values of the field are sufficiently big (comparable with the
Planck units), under the condition of the tensor field's slow change in the
beginning the regime of the quasiexponential inflation can exist. Numerical
solutions for the inflationary stage are obtained that confirm the validity of
the approximate solutions. Inflation takes place under wide range of initial
conditions provided that the tensor field satisfies the condition imposed on
the initial values of the tensor field ${\phi^0}_0(0)\approx -{\phi^i}_i(0)$
(i=1,2,3). That condition also arises from the requirement to satisfy existing
observational data.
