Query: Self-consistent approach to the description of relaxation processes in
  classical multiparticle systems   The concept of time correlation functions is a very convenient theoretical
tool in describing relaxation processes in multiparticle systems because, on
one hand, correlation functions are directly related to experimentally measured
quantities (for example, intensities in spectroscopic studies and kinetic
coefficients via the Kubo-Green relation) and, on the other hand, the concept
is also applicable beyond the equilibrium case. We show that the formalism of
memory functions and the method of recurrence relations allow formulating a
self-consistent approach for describing relaxation processes in classical
multiparticle systems without needing a priori approximations of time
correlation functions by model dependencies and with the satisfaction of sum
rules and other physical conditions guaranteed. We also demonstrate that the
approach can be used to treat the simplest relaxation scenarios and to develop
microscopic theories of transport phenomena in liquids, the propagation of
density fluctuations in equilibrium simple liquids, and structure relaxation in
supercooled liquids. This approach generalizes the mode-coupling approximation
in the G\"{o}tze-Leutheusser realization and the Yulmetyev-Shurygin correlation
approximations.
