Abstract: The fluctuation dissipation theorem FDT is studied close to the glasstransition in colloidal suspensions under steady shear. Shear breaks detailedbalance in the many-particle Smoluchowski equation, and gives responsefunctions in the stationary state which are smaller at long times thanestimated from the equilibrium FDT. During the final shear-driven decay, anasymptotically constant relation connects response and fluctuations, restoringthe form of the FDT with, however, a ratio different from the equilibrium one.
