Abstract
A quasihydrodynamic approximation is introduced for senior memory func tions in the chain of non-Markovian kinetic equations for time correla tion functions in many-body systems. This approximation allows to desc ribe complicated high-frequency and short wavelength spectra for a wid e range of phenomena: from the molecular scattering and the scattering of slow neutrons in liquids to the description of the decay of magnet ic induction signal in crystals.
