  In the mode coupling theory of the liquid to glass transition the long time
structural relaxation follows from equations solely determined by equilibrium
structural parameters. The present extension of these structural relaxation
equations to arbitrarily short times on the one hand allows calculations
unaffected by model assumptions about the microscopic dynamics and on the other
hand supplies new starting points for analytical studies. As a first
application, power-law like structural relaxation at a glass-transition
singularity is explicitly proven for a special schematic MCT model.
