The imaginary part of the dispersion laws of charged collective excitations in plasma (electron excitations in the usual plasma, and quark and gluon excitations in quark-gluon plasma) is discussed. It turns out to be anomalously large—much larger than the inverse free path time that determines...

Effects due to interaction of long-wave fluctuations are studied. The distribution function for fluctuating quantities, making it possible to calculate their correlation functions, is derived. Due to an increasing number of variables, the distribution function is reduced to a form necessary for...
