Description
Time-reparametrization-invariance has been discussed in the
context of glasses as well as different models of spin glasses.
In particular I have investigated this question within the
framework of the spherical p-spin-glass-model, since in this
model at least the equations of motion can be written down
in a closed form. They are closely related to the mode
coupling approach for glasses. At first sight
time-reparametrization-invariant solutions exist in the
aging regime. Investigating, however, short waiting times in
the two-time correlation- and response- functions a unique
solution is selected.
