Cosmology with the SKA -- overview
  The new frontier of cosmology will be led by three-dimensional surveys of the
large-scale structure of the Universe. Based on its all-sky surveys and
redshift depth, the SKA is destined to revolutionize cosmology, in combination
with future optical/ infrared surveys such as Euclid and LSST. Furthermore, we
will not have to wait for the full deployment of the SKA in order to see
transformational science. In the first phase of deployment (SKA1), all-sky HI
intensity mapping surveys and all-sky continuum surveys are forecast to be at
the forefront on the major questions of cosmology. We give a broad overview of
the major contributions predicted for the SKA. The SKA will not only deliver
precision cosmology -- it will also probe the foundations of the standard model
and open the door to new discoveries on large-scale features of the Universe.
