Synergy between the Large Synoptic Survey Telescope and the Square
  Kilometre Array
  We provide an overview of the science benefits of combining information from
the Square Kilometre Array (SKA) and the Large Synoptic Survey Telescope
(LSST). We first summarise the capabilities and timeline of the LSST and
overview its science goals. We then discuss the science questions in common
between the two projects, and how they can be best addressed by combining the
data from both telescopes. We describe how weak gravitational lensing and
galaxy clustering studies with LSST and SKA can provide improved constraints on
the causes of the cosmological acceleration. We summarise the benefits to
galaxy evolution studies of combining deep optical multi-band imaging with
radio observations. Finally, we discuss the excellent match between one of the
most unique features of the LSST, its temporal cadence in the optical waveband,
and the time resolution of the SKA.
