Query: Galaxy-galaxy lensing in clusters: new results   A synopsis of the recent results from our study of galaxy-galaxy lensing in
clusters is presented. We have applied our analysis techniques to the sample of
HST cluster-lenses that span a redshift range from redshift 0.18 to 0.58. We
find that there is evidence that the total mass of a typical early-type cluster
galaxy increases with redshift. For the lowest redshift bin, a sensible
comparison can be made with field galaxies and it is found that cluster
galaxies are less massive and less extended than equivalent luminosity field
galaxies. This agrees broadly with the theoretical picture of tidal stripping
of dark matter halos in high density cluster environments. We also find the
following trends -- at a fixed luminosity both the mass-to-light ratio and the
fiducial truncation radius increase with redshift from redshift 0.18 to 0.58.
