Abstract
In ordinary fluids the angular time correlations between even irreducible symmetric tensors of rank 2l(l≥1) decrease at large times like t32−5l and t−5l, according to whether one considers "bulk" or "self"-correlation. This slow decay is a new manifestation of the hydrodynamical phenomena that govern the asymptotic behavior of autocorrelation functions.
