Within the description of correlation functions in dense fluids, the dynamical laws arise from glass-transition singularities. The simplest such singularity yields a master function with a two-step decay. Higher-order singularities allow for logarithmic decay laws, while multiple singularities give rise to complex master functions. While the scenarios with multiple singularities appear relevant for colloids, liquid water, and granular matter, the simple two-step scenario may be identified within simple models that allow for analytical calculations.
