Abstract
We have computed the time-dependent susceptibility for the finite-size mean-field Random Orthogonal model (ROM). We find that for temperatures above the mode-coupling temperature the imaginary part of the susceptibility obeys the scaling forms proposed for glass-forming liquids. Furthermore, as the temperature is lowered the peak frequency of decreases following a Vogel-Fulcher law with a critical temperature remarkably close to the known critical temperature where the configurational entropy vanishes.
