Abstract

We propose a two-field inflationary model with the induced gravity term. Using conformal transformation of the metric, we get the chiral cosmological model with two scalar fields. We demonstrate that the constructed inflationary model do not contradict to observation data and is suitable for primordial black hole (PBH) formation. The estimation of PBH masses allows to consider PBHs as dark matter candidates.
