Abstract

The correlation functions near higher‐order glass‐transition singularities are discussed for a schematic two‐component model within the mode‐coupling theory for ideal glass‐transitions. The correlators decay in leading order like −ln(t/τ) and the leading correction introduces characteristic convex and concave patterns in the decay curves. The time scale τ follows a Vogel‐Fulcher type law close to the higher‐order singularities.
