Abstract
SKA will be a major step forward not only in
astrophysics, but also in precision cosmology. We show how
the neutral hydrogen intensity map can be combined with the
Planck measurements of the CMB power spectrum, to provide a
precision test of the inflaton potential. For a
conservative range of redshifts we find that SKA can
significantly improve current constraints on the Hubble
slow-roll parameters.
