Abstract
Within the mode-coupling theory for the evolution of structural relaxation in glass-forming systems, it is shown that the correlation functions for density fluctuations for states at A3- and A4-glass-transition singularities can be presented as an asymptotic series in increasing inverse powers of the logarithm of the time t: Φ(t) - f α σi gi(x), where gn(x) = pn(ln x)/xn with pn denoting some polynomial and x = ln(t/t0). The results are demonstrated for schematic models describing the system by solely one or two correlators and also for a colloid model with a square-well- interaction potential.
