For the former situation the relaxation times increase strongly with decreasing distance from the wall whereas in the second case they strongly decrease. We use this dependence to extract various dynamical length scales and show that they grow with decreasing temperature. By calculating the frequency dependent average susceptibility of such confined systems we show that the experimental interpretation of such data is very difficult. %G English %L hal-00113269 %U https://hal.science/hal-00113269 %~ CNRS %~ UNIV-MONTP2 %~ LCVN %~ UNIV-MONTPELLIER %~ UM1-UM2
