Effects of voids on the reconstruction of the equation of state of Dark
  Energy
  We quantify the effects of the voids known to exist in the Universe upon the
reconstruction of the dark energy equation of state $w$. We show that the
effect can start to be comparable with some of the other errors taken into
account when analysing supernova data, depending strongly upon the low redshift
cut-off used in the sample. For the supernova data alone, the error induced in
the reconstruction of $w$ is much larger than the percent level. When the
Baryonic Acoustic Oscillations and the CMB data are included in the fit, the
effect of the voids upon the determination of $w$ is much lessened, but is not
much smaller than some of the other errors taken into consideration when
performing such fits.
