Abstract
It is shown that the deviations from the dynamic scaling, observed in the frequency dependence of the ultrasonic attenuation αλ(ω) just above Tλ of liquid 4He and the temperature dependence of the relaxation time τ(t) of the order parameter, are interpreted in a unified way on the basis of the dynamic renormalization group analysis of Model F introduced by Halperin, Hohenberg and Siggia.Keywords
