Gamma-ray variability and correlation properties of blazars observed
  with Fermi LAT
  The Fermi Large Area Telescope (Fermi LAT) provides long term systematic
monitoring observations of the gamma-ray emission from blazars. The variability
properties and the correlation with other wavelength bands are important clues
for the evaluation of blazar models. We present results from timing and
multiwavelength correlation analysis and discuss differences between blazar
classes.
