Abstract
A general formalism describing the kinetics of relaxation and retardation in glass-forming materials is developed. By introducing the real flow behaviour of a particular system into an extended analogue of Maxwell's equation, a set of non-linear relaxational and retardational dependences, applicable to liquids with different structures, is obtained. The Kohlrausch stretched-exponent formula and similar dependences with time-dependent relaxation times are also derived. A comparison with established empirical relations and existing experimental data gives satisfactory coincidence.
